Take a look at the spec details and decide what you want. I think the HP Pavilion dm1-4310nr will suit you just fine, although its around $700. Otherwise go for the Asus Eee PC 1025C at $490.
These are very simple laptops and are light and easy to carry. They should suit your needs just fine, as long as you're sure you aren't going to do any gaming or anything over and above basic office/work functions.
