A friend of mine has just bought one of these on my recommendation. She travels a lot on business, and has been using the machine for about three months now. She says she is absolutely delighted with it.
Frankly, it's a bargain right now. I wouldn't hesitate to recommend it for the type of use you mention. It has a keyboard and a touch screen, so you get the best of both worlds.
It fits neatly inside your budget, too.
