I looked at some of those at Best Buy and Wal-Mart. They look pretty nice for the purpose they serve. I'd probably get one if I could afford it for travel. Unfortunately, the old laptop my work (generously, no complaints) loaned me the last 3 years conked out. So I had to buy my first one recently, so I have to recuperate from that unexpected expense first. I am still getting everything set up on it.
After much shopping with a limited budget, I decided on the bargain priced Compaq Presario CQ60. It has a 15.6 widescreen display and a number keypad. Hopefully, both features will be a plus for work purposes. I don't have my work stuff on it yet to say for sure. I just wish it had XP or 7 on it! Vista drives me bonkers with all the pop up alerts and quirks. I'll probably upgrade to 7 asap if it isn't too pricey.
I read recently that Sony was getting in the "netbook" game. I'm sure they'll cost more though.
