Ps3 phat 80gb vs ps3 slim?

-whic is better, i hear so many people keep saying fat ones sexier blaa blaa please i want real answers, well i own too ps3's one for jb and one for main psn and everything, they are both the big phat models, both in my room, ones 60gb plays ps2, and 80gb which does not, is it worth if i swaped my phat 80gb ps3 to swap for a slim 120gb ps3? and add bit mre xtra pounds 拢, i will already have one phat then will be one phat one slim, do you think it is a good idea? or is it better if i keep the phat 80gb instead and have both them phat.Your 80gb PS3 can be upgraded into 100GB and more. Change the hard drive of your 80GB PS3 and it's even better than the 120GB slim PS3. You can buy the hard drive(laptop hardrive) 100GB+ on eBay. Having the 'Fat' PS3 and more GB is better than a slim PS3 with only 120GB.
