I feel like I should be taking advantage of the fact I could easily (and cheaply) upgrade my 80GB HDD to 160GB or more. The thing is - I am not sure how I'd take advantage of it. My music is all in iTunes, and so that makes it difficult to stream over. TV shows and (some) movies as well. I delete the game data (but not the saves) after I am done with a game. I have a few downloaded PSN games, but not enough so that I am in a space crunch. So what am I missing? What do you have on your PS3?
