Been using the beta since the day it was released, and I have to admit, that the most noticeable and appreciated change was the notification system. However, the other day, I noticed an app on my iPad that I didn't remember installing. Did a quick test and sure enough, every time I buy an app in iTunes, it is automatically downloaded and installed on my iPad and iPhone without any assistance from me. I know it's a little thing, but it it great to not have to sync after you buy an app just to install it.
