Sorry if this has been asked before, I did go back over the last 10 pages and found nobody asking.
Anyway, I'm going to buy a PS3 today but not sure which version to get, 40/60/80gb. I just want to know how quickly the 40gb would fill up really? What do you really need to use it for? Do you install games, the same as with a PC, or is it just for saves and downloadable content? I'll only be playing games and watching bluray so I won't be downloading films or anything to the HDD, which makes me think 80gb is overkill.
Cheers
