Seriously man, just let it go. I'm sure we all understood what he was trying to say.
On topic: My favorite use for my phone camera is for barcode scanning. I frequent a local tech store that has an insane price-matching policy, so its really nice to be able to scan the barcode and check quickly if there's a better price elsewhere.
I have tried using it as a webcam a couple months ago, and while it worked, it drained my battery too fast to be of any practical use.
