I have an Eee. I would NOT repeat NOT repeat NOT consider it as a laptop for note-taking or, even worse, exam-taking. It's a great little gadget, but the tiny and poor-quality keyboard means that you will have to carry a separate USB keyboard around for any real work. The built-in keyboard is simply too small to type on, and the keys don't respond very well (i.e., you press a key, nothing happens. You push it hard, and the computer gets the idea that you really, really meant to type something, and puts in two characters.)
The other problem is that the extremely tiny screen (800x480) is simply too small for most needs.
They are coming out with a larger version (nine inch screen, I think it's 1024x600) which MIGHT address these issues, since the keyboard will also be larger. Even so, if the keyboard is as of poor a quality as on the 701 models, you still might need to carry a separate real keyboard around.
