Touch screens do require more precision for some tasks, but buttons require pushing the same thing in the same way hundreds of times in an hour. I spend a lot of time turning pages compared to very little time navigating menus. What works best certainly depends on the type of arthritis, but mine includes the base of my thumb. I learned with the very first reader I used (Sony 505) that pushing a button quickly became painful. I use PRS+ with my 650; a light tap anyplace on the right half of the screen turns the page. With lots of different ways to hold my hands and still tap the screen combined with no pressure required, I can comfortably turn pages for hours. I think that touch screen combined with a few key buttons is ideal.
