For the same reason I did.
I updated my Droid X because I has having significant slow performance problems. The upgrade did fix the problems. However my phone is no longer rooted and I am unable to root the phone at all now. I am mindful of applications runing and keep the number to a minimum, I mind the memory as well. The Droid runs great now but I have to put up with Blockbuster wanting to constantly be updated. That Applications is an annoyance to me plus I never use it.
I will be available to upgrade to a Droid Razor Mazz soon so it will be interesting to see which is available first a root for Gingerbread 4.5.621.MB810/ Build 4.5.1_57_DX8-51.
or a new Razor Maxx.
