So i guess the size difference is close to a factor of 2 in RISC systems, but in CISC, it's like to be just about 15-20%. Anyway, those X driver issues a couple of posts mentioned are scaring me. It probably means no DVD watching and no PC games. Given that, i think i'm gonna go for 32-bit laptop for now. I spent enough time setting up my previous 32-bit box, and even though i wanted to test out 64-bits, i don't think i can afford it timewise. Thanks.
