PS3 Experts only! All about the different GB models, with details. No MS fanboys, please...?

20GB I don't recommend because of the small amount of memory. The 40 GB is what I have, the only reason I wanted it was because it had a playback feature for all of my old PS2 games (it has been discontinued so the only place you will find it is on the internet). The 60GB, 80GB, and 120GB I don't like because of the lack of playback feature and the price. Personally I could never use that much memory.
