The original Kindle Paperwhite launched in 2012 with a slightly improved version released in late 2013. Now the Paperwhite has been given a decent upgrade for 2015 in the form of a much higher resolution screen and a new font. See: 7 best e-readers you can buy in 2015
Amazon Kindle Paperwhite 2015 release date
You can pre-order the new Paperwhite immediately but it will ship on 30 June, just a couple of weeks away. It will also be on sale at Dixons, Argos, Tesco, John Lewis and Sainsbury's.
Amazon Kindle Paperwhite 2015 price
The Wi-Fi only version retains the usual Paperwhite price of £109.99 but you can add £10 if you don't want those 'special offers' - otherwise known as adverts on the lock screen.
There's also a 3G + Wi-Fi model which costs the same as the old model did at £169.99. Again, it's £10 extra to remove ads.
Amazon Kindle Paperwhite 2015 specifications
The new screen is the key highlight here. It has the same 6in diagonal as ever, but packs in more pixels to hit 300ppi instead of 212ppi for the old model. This means it has the same great clarity as the Voyage, but without the need to spend an extra £60.
Amazon isn't explicit about the actual resolution, but if it's identical to the Voyage, it will have 1440x1080 pixels rather than 1024x768 on the outgoing Paperwhite.
It does make a difference and given it's no more expensive, it's an upgrade well worth having.
In every other respect, the "all new" Paperwhite is exactly the same as the preview two generations. The dimensions and weight are the same, as is the overall design. This means it should fit into existing cases made for the Paperwhite.
No figure is given for internal storage, but few people will run out of space as there's still room to store thousands of books.
Wi-Fi appears to be identical too, supporting 802.11n, g and b standards. The 3G model has a built-in SIM as before for downloading books from the Kindle store wherever you are.
The new Bookerly font is meant to be easier to read on a screen than other fonts, and also scales better to be more readable at smaller sizes, Amazon says. With the higher screen resolution this should mean you can fit more words onto each page without reducing readability, and that means fewer page turns are necessary.
An ambient light sensor allows the new Paperwhite to adjust the front-light brightness to adapt to changing lighting conditions, just like the Voyage.
One of the features which will be available "soon" is a new typesetting engine which positions the words as the author intended and makes books look, well, more book-like. It includes improved hyphenation, justification, kerning, drop cap support and ligatures. If you know what all those mean you're a typography geek, but everyone should be able to appreciate the improved look.
