I've been waiting a long time for the Nvidia 8-series to reach laptops before looking to replace my 2 1/2 year old Dell XPS M170, which has been absolutely wonderful for gaming (mostly BF2, BF2142 and COD4). The 7950GTX wasn't much faster than my 7800GTX, but the 8800GTX looks like a good upgrade for future games (along with replacing my Pentium-M with a Core 2).
I just hope that someone releases a more mobile 15.4" or smaller laptop with this card (8800 GTX or GTS version). I'm not sure about other people, but I usually have my gaming rig plugged into an external LCD/keyboard/mouse when I'm at home, so I really don't need a 17" screen most of the time. A 15.4" screen might seem a bit small for gaming, but it would be a heck of a lot easier to game with on an airplane or in the back seat of a car, where I find the 17" a bit too large.
Anyway, eagerly awaiting more laptops with these cards.
