I'm a student doing a PhD. Got my own desktop with 22" screen and 2nd 15" (I think) monitor in front of me all day. Have a 15" laptop and another desktop with 22" screen at home. I'm still actively planning on getting an eBook reader.
Computer monitors are just not nice to work off. Plus I find it tiring to sit in front of a computer all the time. It'd be nice to be able to switch it off and do some reading of papers, tech books, etc.
I can see your point that it's unlikely that every college student will want to splash out on a laptop and reader at this point though. They're still a bit on the expensive side. But you could say the same about laptops when they first came out. Why buy your own laptop when the college provides computer labs free of charge?
It's a new technology. It'll take time to enter mainstream. I think they have the potential to be massive though. Might save my poor back carrying around loads of books
