Hi, I'm considering trading in my Xbox and PS2 for a PSP at Electronic Boutique. I can get 60 bucks for each console, and throw in a little of my own cash and get a PSP, it's very tempting. But, I don't know much about the PSP. What all can it do? I see that I will need to buy an extra Memory stick and a USB cord. And it seems to work with OS X. Obviously, I'm a n00b with this thing. How does it "browse the web?" that must cost extra ...right ? and transfering files from the Mac....can it be used like a portable HD and transfer files from my Mac at home to my PC at work? are the games good? I like RPG's a lot, and sports games... Any replies would be appreciated. Thanks !
