You can keep thumb rested on a button and only give a little pressure to turn page.
Can't do that w/touch. Must move thumb, and if thumb is being used to stabilize device, moving it becomes unstable. Not a problem for everyone, but if you have to read while flat on back or other weird positions, it's annoying.
If you hold the Touch with your thumb on the edge of the bezel, it takes only a small rolling movement of your thumb to turn the page. Just as easy as pressing a button.
