The iRex Iliad has a touch screen and stylus input, so it seems that it can be done. Judging from the experiences on the Iliad forum, however, "digital ink" input requires lots and LOTS of screen refreshes which reduces the time between charges to only a few hours.
I think personally that you are right - for a fiction book reader (which is what the Sony Reader is), hardware buttons work a lot better than a touch screen. They don't require screen refreshes to operate and there's also the benefit that the
lack of a touch screen makes the device a lot physically "tougher".
