I've had a MSI Wind U-100 that has worked flawlessly since I've owned it. I use it in my mini-mancave every night, and take it with me to the B&M often to use it with their wi-fi.
I did upgrade to the 6-cell battery for longer life, but I also purchased an extra power supply that I leave out in my mmc so I can just plug it in when I go out in the evenings. The other thing I did invest in was a Logitech wireless mouse, as I hate touchpads.
Netbooks are excellent if you need something to surf the web, check and answer email and move it around alot.
