I need help picking out a laptop. My budget is $1500, but hopefully I don't have to pay that much to get what I want. It will mostly be used for school purposes... note taking, power point viewing, internet researching, etc. I'm going to be carrying it to and from classes so I'd like it not to be very heavy... but I also would like it to have a big screen. It doesn't need to have a big hard drive, but I'd like it to be decently fast. I'd also like it to have a fast CD burner and a good wireless connection. A 4 hour battery life would be nice, although I don't know how feasible that is. I have no idea which brands are supposed to be the best, or even whats available these days. Anyone got any advice or suggestions? I NEED THEM. thanks a lot!
