I've been growing kind of frustrated with my 40 GB PS3 and the lack of hard drive space with it, and last night I had an idea. I was thinking that I could take the 40 GB model in to GameStop and trade it in for in store credit, and then buy one of the new models. Taking all my save data and storing it on a USB drive wouldn't be too difficult, but I'm wondering if you guys think it's worth it.
I read somewhere that it is possible to upgrade the hard drive space, which I'm sure would be cheaper, but I have no clue how to do this or if it's possible on my particular model.
