Asus EEE EA-800 (aka Asus EEE Note) is definately something you should check out too.
It's not an eInk Reader in the pure sense (no eInk screen but a black-white LCD screen) but it does seem like a device that is specifically targeted at students, great for note takeing, also good as an eBook reader (8" screen), it has Wifi support and a browser.
If you are going to do a LOT of note taking than it could be the device for you.
Things you can do with it :
Note taking
eReader
Camera
Voice and Sticky Memo
Photo album
Music Player
Dictionary
Web Browser
Two Games and a Calculator
