I was thinking about getting a Playstation 3 but I don’t really know much about newer game systems. The new ps3 is available in 120GB and 250GB. The problem is I don’t know which size to get. The 120GB is $299 and the 250GB is $349. I’m not a gaming fanatic or anything but I still don’t want to want to run out of space. I heard that some games require 4 or more GB to even install. I pretty much just want to play rock band. What is the hard drive used to hold besides pictures and music? Is is worth the extra space to pay a little more? Which size do you recommend I get? Can someone explain in simple terms please? Thanks.
