I like Dell and IBM a lot, though some people complain about IBM's laptop RMA policy. Its really a matter of personal preference though, every laptop maker and model has its pluses and negatives. Personally I like the C400 from Dell a lot.
I think that Toshiba and Fujitsu are flimsy. Toshibas feel and look like junk in my hands, and I can see that the Sonys are high quality but I hate their look and too small feel. Odd, I don't actually like any of the Japanese laptops, maybe its because I'm a big white guy, but I dunno.
Do you guys find yourselve having a bias, like how the Japanese hated the big Xbox controller?
