>From what I've read in the net the big problems are things like the
laptop keeps running when you close the lid, not the correct resolution
on the screen and a whole bunch of minor, but very important details.

And, since most pc's and laptops are sold with a system and that system
being Windows, well you pay for win even if you don't use the
thing :( And that is not something I'd do, buy something i do not use.
