Also, AMD's are not very good for laptops right now, require to much power and exhaust too much heat.
Don't know about that. My moms laptop smokes my dads. his is a 2GHz Intel and hers is a 1.8GHz 35w 2400+XP-M, considering the XP series is the high end of the previous gen chips, then that's a nice little addition making the laptop pretty powerful.
I don't know whats inside my dads, celeron or centrino? Which I have no clue on the centrinos but the celeron would be the low end of Intel so that'd be like putting a duron in the laptop.
Hers will put out some heat though when my friend would game on it, but a notebook cooler brought that down considerably.
