Questions:
* How much was it at Dell?
* What's the difference between Stick, Stick Pro, Stick Duo, Stick Pro Duo? I don't have a PSP, but we just bought a digital camera that uses the stick. It came with a 32MB one, which is not enough; we're looking at either 512MB or 1GB, but before I drop ~100 bucks on one, I would like to know the difference [it wasn't too long ago that I was happy about getting a 32MB CompactFlash for 60....]
