At 8.99 ounces, it's fractionally heavier than the K3, but still light enough for easy one - handed reading; that's probably a good trade - off to get a larger screen (which
means more words per page and fewer page turns when reading, especially if you like to read at larger font sizes).
In total, it seems like I'll get 25 - 33 %
more words on the K3 screen, which is great for a few reasons: having to press the
page turn button less frequently (which is nice in itself) also
means I should be able to read faster, and the battery will last longer, since e-Ink screens only use power when you change
pages (you should get about 10,000
page turns
per battery charge, regardless of how many
words are on each
page).
Eric Saarnio, head of Amazon devices in the EU said: «It has a 7in screen, an inch larger than any of our recent devices, and is also the highest resolution with 300ppi screen density,
meaning we can fit around 30 %
more words on the screen
per page, which
means customers have to turn fewer
pages.»
