I disagree, first of all it's easy to replace/upgrade parts on a desktop. On a laptop about the best you can do is upgrade memory and the hard drive. The power of the hardware is definitely way more limited no matter how much money you're willing to spend. You sure won't be seeing Kentsfield CPUs in any laptop or a Quadro 5600 FX or 8800 GTX Ultra card for that matter. And I promise you that no laptop today can play Crysis on Very High settings at 35+fps.
