Yeah, I probably went too far. I don't know about other manufacturers, but i'll give you my opinion about those who I know.
I have an
HP, there are only 3 things i dislike about it: the dvd drive is a samsung, the hdd is a bit slow and the screen is good but i've seen better. Best speakers i've seen in a laptop.
I love the
Sony Vaio's screen but those are more expensive, the overall quality is good.
I've never tried
IBM's because most of them have a smaller screen than the usual, and are more expensive.
Compaq, as usual, stay away from it

(even thou I haven't tried any product after their merging with HP).
Dell seems to be the big deal actuall, good screen and components, battery life on centrinos is good and the price is unbeatable.
Toshiba, those are really good but their cd drive is likely to fail or not read some discs with time, the speakers are crap.
