The USB ports? They're used to plug in microphones, Rock Band's (soon GH4's) drum kit, and headsets for online gaming. I think some old online games were compatible with a USB keyboard too.

Used for connecting a USB HDD, and running ISOs/games off it, if you use Swap Magic or have some kind of memory card exploit to run off it.

1.Take USB
2.Bin it
3.Buy PS3
4.??????
5.PROFIT!

This man fails.

I've used that port to plug in my guncon controller for the Time Crisis games, and the rare time when I've felt like it, my Dance Dance Revolution pad.
