OK, I see. I am wondering if any laptop could see the light of day in the fortcoming future that would sport a GPU on par with the 5850 and that would weight as much as 2.4 - 2.9 kg, while being unexpensive. Is this a dream ? Or is it bound to happen this year ?
They have some models with respectively 460M/485M GPUs. The 485M is a beast. The 460M is on par with a Mobility 5870. I still think that the 460M models are a bit expensive. I'd even skip anything that has a i7 CPU.
Prices start @ 1400 $. If you add 500 $, you get the same laptop but with a 485M.

The thing that bugs me : why can't you just gimp the CPU down in those customizing options ?!
