According to this article, Verizon is stripping some stuff out of 2.1 such as the "conveyor belt" launcher, and live wallpapers. Those that are patiently waiting for 2.1 may be disappointed in the final release. Me, I'm perfectly happy with Bugless Beast which has all of the features that I liked from 2.1. Solved the problem for me about unrooting or not.
