Is the Kindle Paperwhite 4 being released?

Its been two years since the Kindle Paperwhite three release, so we are due an update. There is a picture and information leaked, via a Chinese retailer, of a possible Paperwhite coming out. Information is sparse, other  than a water-proof device, a flush display, the same 300PPI and what appears to be, again, a six inch screen. This is speculation, and I can be very wrong, but I think the leaked information is generally correct. The information provided is consistent with Amazon's strategy of keeping the six inch size and introducing small incremental updates.

The leaked information also noted two further more premium Kindle devices for 2018. One is a six inch e-reader - possibly replacing the Voyage - and a high-end seven inch one. Again, I think the leaked information could be right. Specifically, a seven inch Kindle - to replace the Oasis - may finally provide something to entice e-readers to choose a high-end e-reader over the Voyage and Paperwhite.

Thoughts on Canonical cutting its convergence & Ubuntu mobile projects

Canonical announced - the people behind Ubuntu - it will no longer work on convergence and Ubuntu Mobile; instead the focus will be on Ubuntu desktop and to support private Linux cloud infrastructures. In the words of Mark Shuttleworth (founder of Ubuntu and Canonical):
I’d like to emphasise our ongoing passion for, investment in, and commitment to, the Ubuntu desktop that millions rely on. We will continue to produce the most usable open source desktop in the world, to maintain the existing LTS releases, to work with our commercial partners to distribute that desktop, to support our corporate customers who rely on it, and to delight the millions of IoT and cloud developers who innovate on top of it.
The focus on the desktop also entails a move from Unity to the GNOME desktop interface. Considering larger projects to enter the mobile world failed - e.g. Microsoft and Mozilla - it makes sense to change direction. However, concentrating on the desktop PC is not the way forward.

I would like to see Ubuntu differentiate their operating system to meet the demands of different users - this includes the desktop PC but also entry-level laptops and two-in-one devices. The popularity of the entry level laptop - e.g. the HP Stream series - identifies a use-case scenario in the laptop segment. Linux - less resource intensive, compared to Windows - is an ideal operating system for this segment and Ubuntu could adopt a version of the operating system to ship with similar devices. For example, further developing Xubuntu - with its lightweight XFCE desktop environment - is a viable option for devices with low-end hardware (Xubuntu's current interface is out-dated and doesn't work well with low-end Intel processors that ship in entry-level laptops).

Further, while Ubuntu Mobile is now discontinued, Canonical could also develop a touch optimised version of Ubuntu that is cloud-centric and directed towards two-in-one users. Before Chrome OS, there was Joli Cloud OS - a Linux operating system that aggregated the user's different web-based services in one place. With the popularity of the touch enabled two-in-one devices, a touch enhanced, cloud-centric version of Ubuntu would be a welcome addition to Linux. Google realised the direction of computing and developed Chrome OS - an operating system that is based on Gentoo Linux.

Re-thinking the Linux operating system would also contribute to a stagnated Linux world in which efforts are replicated in the release of too many distributions. To be sure, developing the GNOME project is necessary but this should be part of a broader effort to move beyond the traditional PC desktop operating system. Convergence was an attempt to contribute to this different direction but the hardware is still not mature to make the idea work. Differentiating the Ubuntu operating system, however, is a viable path in the PC connect era.

Kobo Aura One Review: Despite the flaws, the Kobo Aura One stands-out in the small world of larger e-readers

The Kobo Aura One’s 7.8 screen E-Ink Carta display makes it unique; it is the largest e-reader released by a major vendor since Amazon’s Kindle DX. Expectantly, demand is high. In this review I will focus on the software side and if it maximises on the different use-case possibilities of a larger display.


The 300 PPI display is crisp and sharp. One minor complaint is the Aura One’s flush tablet-like display that slightly affects text contrast – this is possibly due to the screen’s extra layer. Overall, in my view, a flush display does not work with an e-reader screen. The front-light is impressive and uniform, considering the larger eight inch display, and compares well to the Paperwhite (see comparison pictures between the Aura One and Kindle Paperwhite).

An innovative feature, since followed by Tolino with its Vision 4 HD, is Kobo’s ‘Comfort Light’. In the words of Kobo, the Aura One “senses how much light is available, and can automatically adjust the brightness level for you. It can also change the colour of the light”. The auto-brightness light sensor is not new, with Amazon introducing the same feature with Kindle Voyage; what makes ‘Comfort Light’ innovative is the ability to change the colour of the front-light to match the time of day. This feature is similar to blue light filters that many vendors, including Amazon, release with their tablets. I personally turn off the front-light when using an e-reader – to avoid any light emission – but it is a useful feature to ease eye strain for users that don’t mind reading with the front-light on.

Battery life is a negative point. I would estimate the battery life, with both WiFi and front-light turned off, to be between Amazon’s Paperwhite and Android e-readers. The Icarus XL that I reviewed, for example, required a charge within three days of regular use. From my experience, the Aura One has superior battery life compared to the Icarus XL but is significantly behind the Paperwhite. When the Kobo Aura One was released, many users reported problems with excessive battery drain in stand-by mode or when syncing the device. However, a number of updates were since rolled-out and these helped with the battery problems. A problem I noticed – a possible firmware bug – is a sudden ten percent drop in battery when reading – possibly due to background tasks running – and so you need to be mindful that the device is not always reporting the correct battery state. A positive is that the Aura One re-charges quick, compared to other e-readers.

Overall, Kobo clearly put serious thought and consideration with the Aura One’s hardware design and development. The front-light is impressive and uniform for its larger size – far better than the Icarus XL – and the display quality compares well to Amazon’s Kindle Paperwhite. Also, the device, according to Kobo, is water-proof for up to 60 minutes in up to two meters of water.

Nickel – Kobo’s operating system – feels under-developed. First, I will state the positives with Nickel, followed by some problems that I experienced:


(1) Enhanced typographical options – In comparison to Amazon, Kobo offers some extra typographical options. The user is able to add fonts and change both font weight and text alignment. However, changing font weight, without patching the firmware, is not available with side-loaded fonts.

(2) Pocket & Overdrive integration – It is possible for users to sync their saved articles via Pocket integration, to then read on their device. OverDrive integration allows the user to borrow e-books from their local public library to read on the Aura One.


(1) Amazon, understandably, due to scale and size difference, offer superior cloud services. For example, with all Kindle devices, the user is able to sync their e-mailed personal e-books (this includes bookmarks, notes and highlights). Further, when the user emails a document to their device it is then available through the recently released Amazon cloud drive. Kobo, with some consideration, could offer similar services through integrating Nickel with external cloud service providers e.g. Dropbox. Kobo already allows user to send and sync online articles via Pocket integration and so further integration with other services is a viable option.

(2) PDF support is poor – Kobo, similar to Amazon and Barnes & Noble, aim to tie their users to their own e-store. Amazon, however, considers PDF support and offers good features e.g. highlighting, taking notes, translation and increasing PDF contrast. While Amazon’s range of Kindle e-readers may be used as a viable PDF e-reader this is not the case with Kobo. Nickel’s PDF software is, at most, a basic viewer, with no way to interact with the text. There is no possibility to highlight or make annotations and both scrolling to navigate and pinch to zoom are erratic. Another problem, is the lack of tap to scroll and so to scroll the user needs to drag down the screen; this is cumbersome and slow with E-Ink.

(3) Problems with EPUB rendering – Kobo’s e-books come in their own propriety format – KEPUB. KEPUB books render well and are responsive to changes in margins, line spacing and offer further typographical options. However, with EPUB e-books, surprisingly, considering KEPUB is based on EPUB, the Aura One rendering is poor. Basic settings, e.g. margins and line spacing, are not responsive to changes in reader settings. This poor EPUB rendering means it would be better to convert side-loaded e-books to Kobo’s native KEPUB format via Calibre – this isn’t a problem with a few e-books but those with large libraries may find the process a hassle. Amazon, adopt a propriety format of MOBI, with their own e-books, but you still get near identical support with side-loaded MOBI e-books. Of course, Amazon adopting MOBI and not supporting EPUB is a definite negative. 

(4) No direct way to export notes and highlights – There is no way to export personal highlights and annotations or to store the exported content online. Amazon, in comparison, with both personal and purchased books, via their Kindle Application, allow users to export their highlights and annotations to Evernote or via email; further, there is the option to create flash cards for revision. To support similar features, it is possible for Kobo to develop a partnership, similar to Pocket, with Evernote. The partnership would then allow the user to store a notebook of their annotations and highlights in the cloud via Evernote integration. Established Android e-reader applications – for example, Moon Reader and Bookari Reader – allow users to export their annotations to their favourite note taking application.

(5) Forced header and footer – By default there is no way to disable the header or footer – both take up a portion of screen estate. It is possible to add a patch to disable both header and footer but the full-screen patch, sometimes, cuts the text at the edge of an e-book. The issue with a header and footer, in my opinion, substantiates the central problem with Nickel – an operating system with some stand-out features, e.g. Pocket, Over-Drive integration and extra typographical options, but with under-developed and limited e-reading features.

(6) Navigating device folders – This feature is neglected by both Kobo and Amazon. It is possible to organise your side-loaded through folders but there is no option to navigate these folders on the device. Kobo allows the user to create collections, to categorise both purchased and side-loaded books. However, unlike Amazon, Kobo only syncs purchased books to the created collection.

(7) Highlighting text is cumbersome and you need to be careful when dragging to select the required passage. Further, there is some lag when entering text for annotations.

I think the major problem with Nickel is that it was designed primarily to support purchased Kobo e-books and is directed at leisurely reading. Users who wish to use a Kobo device as an all-round e-reader, to interact and engage with an e-book, will find the device’s firmware limiting. Many features, noted above, are easily integrated into Nickel but it seems that Kobo’s views their primary goal to sell fiction e-books (similar observations may be applied to other vendors). I would still say Kobo’s support for KEPUB is good – specifically its expanded typographical settings that others don’t offer – and so the Aura One, despite the noted limitations, is a viable e-book reader. However, the same cannot be said in regard to PDF support.


Unfortunately, due to poor PDF support, installing KOReader is a necessity if the user requires a functional and feature rich PDF reader. Below are some issues to consider with KOReader:

(1) Battery life in KOReader – Compared to Nickel, KOReader is not yet optimised with the Aura One. In comparison to Nickel, and this applies to PDF reading, I noticed the battery drains quicker. In other words, expect battery life to be reduced if you intend to use KOReader regularly. However, there are regular nightly releases of KOReader and battery life continues to be improved. If you are willing to use KOReader then, in my opinion, it is the best PDF reader, at the moment, available for E-Ink.

(2) Central PDF features work well in KOReader – PDF text recognition, highlighting, annotation, cropping, increasing contrast and touch to scroll all work well with the Aura One. Also, compared to Nickel, PDF rendering speed is much better. I personally use KOReader exclusively as a PDF reader and export my annotations offline to the device’s storage. Thus, I haven’t tried more advanced features.

(3) The installation process is not difficult but it is not for the novice user – anything that goes wrong with the e-reader, during the installation process, may void the device’s warranty. I would prefer if Kobo offered a viable PDF reader to avoid third party applications but, at the moment, it is only the option for users that want more from the Aura One.

Overall, if you are looking for a larger e-reader then the Aura One is the one to choose. Smaller vendors, e.g. Onyx and Boyue re-branded e-readers, do not match Kobo for hardware quality. Yes, these e-readers offer greater versatility with Android pre-installed but usually the screen quality is sub-par in comparison to the Kobo Aura One – an e-reader is defined, foremost, by its display quality. If Amazon released an eight inch Kindle then it would be, by far, the stand-out choice. At this time, in the small world of larger e-readers, Kobo Aura One is the best option. Fortunately, due to the community driven KOReader project, the user can use the Aura One as an all-round e-reader, despite the limitations of Nickel.


Enhanced typographical options
Pocket and Overdrive integration
Excellent display
Impressive and uniform lighting for a 7.8 inch device
Comfort Light is an innovative feature
Relatively open, with the possibility to install third-party software and patches


Restricted software features
Poor PDF support

 Overall Verdict: 7/10

HP Stream 14 Review: A good value entry laptop let-down by a sub-par display

The HP Stream 11 and 14, late 2016 release, brought something different - the first entry-level laptops released with 4GB RAM. In the US, both the HP Stream 11 and 14 are available with with 4GB; in Europe, unfortunately, only the HP Stream 14 model is available with the extra RAM. The extra RAM that comes with the 2016 HP Stream 14 makes a significant difference when multi-tasking. Make no mistake, the N3060 Celeron Braswell is no power-horse and it would have been better to release this generation of Stream laptops with a Celeron Apollo-Lake processor. However, the Braswell processor offers good enough performance but with some stutter and lagging with more intensive tasks. For example, browsing web-pages with rich multimedia content – CNET being a case point – slows down browsing. I would recommend installing an effective ad blocker to deal with with advertisements/click-bait and automated video content. Further, internet performance is affected by the browser used – Firefox and Opera work better, in Microsoft Windows, in comparison to Google Chrome and, ironically, Microsoft Edge. Chrome works better in Linux than Firefox.

The display, in my opinion, is the device’s let-down. For this category, with an emphasis on portability, a matte display would have been a better choice (the HP Stream 14’s glossy screen is very reflective). The biggest problem with the screen, even in comparison to other entry-level laptops, is its poor viewing angles and washed out colours. The problem is accentuated with a relatively low pixel density in a 1366 x 768 resolution spread across a 14 inch display. The problem can be somewhat remedied through increasing both gamma and colour saturation through Intel graphics. The track-pad works well and scrolling is smooth but the track-pad is stiff when pressing. One plus with this laptop, consistent with the HP Stream range, is a very good keyboard. The keyboard, due to the larger laptop size, is near full size.

Another positive with the HP Stream 14 is that it works ‘out of the box’ with Linux Mint, Ubuntu and Elementary OS. I would recommend Linux Mint Cinnamon for its stability, user-friendly interface and resemblance to a Windows desktop environment. I also noticed a performance boost with Linux, in comparison to Windows; further, most Linux distributions run comfortably with 32GB storage. Battery is very good in Windows – closer to a maximum of 8 hours than the advertised up to 10 hours – but is further extended, with the right tweaks, in the Linux distributions I tried.

The HP Stream 14 is a good laptop and offers value in terms of hardware and a bundled Office 365 subscription. I like the larger screen that doesn’t compromise portability (the laptop’s 1.4 KG is relatively light-weight for its size). However, if you don’t need Office 365 and would prefer something more lightweight, compact and with a higher pixel density then the 11.6 inch Acer ES11 might be the better the option. The device similarly comes with the important 4GB of RAM but with a better processor (Intel Celeron Apollo-Lake N3350). The option of purchasing the Acer Aspire ES11 without an Office 365 subscription means it comes at a lower entry price compared to the larger HP Stream 14.

  • Lightweight for a 14-inch laptop
  • The extra RAM makes a significant difference
  • Very good battery life 
  • One year Office 365 subscription
  • Very good keyboard 
  • Works well with Linux


  • The screen is sub-par, even for this category.
  • The Braswell processor, despite the slight improvement from last year’s model, is still under-powered 
  • Iffy trackpad

Overall rating: 7/10
