There is an abundance of apps in the iTunes store. Some are great, some are not so much and some that just make you wonder. There are apps in every category... EVERY category. To me, this is great. If I think it would be great to have an app that uses the tilt control to turn my phone into a level, I know I can find it (and have). Really, I've said it before and I'll say it again. iPhones are the greatest things ever.
