I seriously don't get why people want buttons (including these side "buttons" with haptic feedback) to turn pages. It's so much more satisfying to turn a page on a Paperwhite with a flick of the finger sliding across the "page" (the screen) like you would do with a book. You can already tap the screen with your thumb (using the same hand to hold the device) to turn a page. Why on earth would you want these ugly lines and dots now on the side of the Voyager reader so you can turn your pages that way?
I had one of the earlier white Kindles with full keyboard, and the buttons is what I miss the most on the Paperwhite. It just feels awkward to move your thumb to the screen and touch, as your fingers get in the way of the screen. On the Keyboard Kindle you can keep staring at the screen while turning pages, with nothing getting into your focused field of vision and achieve a higher flow.
Still, the Paperwhite is good enough that it has been a good upgrade. Touching to define a word or to find out who this character in GoT really is, is very useful.
Alas, the new Kindle does not ship internationally just yet (or at all, until October 21st).
I bought Kindle Paperwhite for my granny. She wants to lie down and read books. However she has fat fingers, and often she would
1) have the holding hand accidentally touch the screen.
2) have the other hand tapped for too long and initiate dictionary mode.
So she gave up using Kindle.
