The Kindle app on Android/iOS already solve this problem, you tap the side of the page and it switches to the next page in the book. I've been reading REAMDE on my Samsung Galaxy S and on my iPhone and it works fantastically. Exactly as you'd hope it would work.

Quick easy to switch from one page to the next, all the whole still holding it in your hand.

I am assuming that the same concept will be brought over to the new touch Kindles.
