I've had my Acer travelmate 4002 since June and I'm pretty happy with it

Dunno where you read those bad reviews. I asked around and several people (some were owners of different brands) recommended Acer.
But, mine can get kinda slow if you're running too many things at once. I don't know if all Acers are like that, but if I had to run a graphics program on my laptop it would probably be a nightmare. However, for my needs (a graduate student who uses it for wireless internet, bluetooth, saving articles and typing papers) it's perfect. I don't like downloading on this computer, I'm paranoid even though I have Norton Internet Security installed. Another thing I like about Acer laptops is that they're relatively light, which is important for me.
Toshiba and Dell are big names also. I think it depends on what you want to do. To my knowledge, graphic design type people prefer macs.
Note: I think most Acers, if not all, have rectangular screens if it makes a difference.. I know a friend of mine prefers square screens and he got another brand (can't remember right now what he has)
Note 2: If you know someone in North America, eBay is your friend.
