To ROOT or Not to ROOT? That is the question

[92greenlx]

i'm new to the android platform, came from a bb, so i'm used to installing leaks and hyb's. just curious if its really worth Rooting to 2.1, i found a site that allows you to downgrade from 2.1 Root to 1.5 stock, so i guess in theory, i can try the root, and if don't like it, downgrade back. kinda sketchy on doing this as of yet, just wanted some opinions on the subject. also what does not work on the rooted 2.1? what works?

thanks
