Heat and power is certainly an issue with this card. I'll admit on a desktop computer, case cooling, water cooling etc can negate the negatives side effects of Fermi, but you can't really do that with a laptop. I have a feeling any laptop attempting to use this card will either have a very short battery life or a VERY large battery. The 480 incarnations have too many side-effects to justify buying one, IMO, and on a laptop those side-effects will become measurably more pronounced. Patiently waiting for a GTX 485...
