I just want a laptop that will actually be decent and won't lag up with 3-4 Firefox tabs, MSN and steam. I've seen good Asus laptops at around $900.
The box may say something like "2.4ghz dual core" or sum such and that may
sound good for a laptop, especially compared to your old one but it's not. Unless you need a laptop (for school, work, whatever) do
not buy one. As far as the technology goes it will be a brick in 2-3 years, not due to being broken but due to being badly out-dated.
Then there is the very limited battery life of using a laptop for anything other than sitting there, most can't even finish a movie unplugged. That Asus won't be able to finish a movie, not if it's only $900. How do i know this? because the good batteries often cost $500 by themselves.
there is no such things as a good, cheap integrated video card. It may claim to have nice specs on the box but wait till you get it home and you can't run blockland because it does not support openGL.
I could go on and on but it's up to you. If you want to look cool hauling around a magic computer box, go ahead. Just remember that you were warned.
Don't buy a laptop unless you need one.
