Okay, PS3 owners. Assuming I am not interested in Motorstorm, and assuming I'm not interested in backwards compatibility of PS2 games, is there any good reason I need to pay the extra $100 for the 80GB? Because if there's not, I'm kinda eyeing the 40GB version and using the extra $100 to upgrade the hard drive to a 250GB drive. I am curious how PSP remote play works though. Is it only PS1 games, or PS2 also? If I buy the 40GB version, will the PS1 stuff still work?
