My Kindle 3 was the first device I ever used with page buttons. I liked them okay. I'd been reading before that on a Palm with a touch screen that scrolled and that's still my preference. I read on my phone with Moon+ set to scroll by touch.
Before that I read paper books. I probably started reading about 1944 so I had a lot of practice reading paper books. I got pretty good at turning pages with the hand that wasn't holding the book.
For those who can't do that I suggest trying to learn. It still works beautifully on today's devices.
My Voyage has fantasy buttons. I can pretend they're there and they work just like buttons, allowing me to turn pages easily with one hand. They seem to work very well but I really see no point in them so except now and then to give them another try I leave them turned off.
I've been watching and reading about the Oasis and I originally decided not to get it because I don't trust that tiny battery, but I keep thinking about it and it's size and shape and I really think I'll like reading on it and that makes me wonder if it's worth giving up battery longevity. Then I examine pictures and videos again and that 40' wide right hand bezel with the buttons changes my mind and I forget about it again, for a while.
If they made an Oasis without buttons or huge right hand clumsy looking bezel I might have an Oasis by now. I really think it's a good design considered strictly in terms of reading. Of course I've never actually seen one so I could be.....well, I was about to say I could be wrong, but nah!
