It's odd that the amd setup is more expensive than the intel setup. The B&M stores have always sold X2 turion notebooks cheaper than their intel core duo counterparts (so what in the word is asus smoking)..
The turion x2 is slower than the core duo at the same clock speed, and is quite a bit slower than the merom. If they stuck an express slot on this setup along with a 7900GS, I'd easily overlook the performance discrepancy for the price
For the price, quite hard to justify it considering the Dell Inspiron 1705 with it's 7900GS Vid card is available for around 1200-1300$.
I wish Asus would make a S96J with the 1280x800 (15.4 widescreen), BlueTooth, DVI, a 7900GS w/ 256MB VRAM for less than 1400$. Shouldn't have any problems gaming at the max res of the screen without issues.
