It seems that getting the ps3 slim would satisfy your need for a larger hard drive, as well as satisfying your need to be an early adopter of "new tech" even though it's the same tech in a different box, lol. Also if you said that trading your current ps3 would allow you to spend pretty much the same amount of money you would on an HDD than it's a no brainer, get the PS3 slim.
PS3 FTW
