It depends really on how much you want to spend.
I would stick with the majors though.
Sony, Dell, Apple, Panasonic and so on.
I would love to have a Power book G4 from Apple. From the people I know that own them say its the best laptop ever made.
Since I use a Windows platform and maybe you, that may not be the case.
An upgraded Dell works good as well but it's a little noisy.
Sony has some nice stuff too.
Research heavy on this because Laptops cost megabucks.
