Do it. Free yourself from all the Motorola and Verizon crap. Just keep in mind sometimes rooting can be more difficult then anticipated, my suggestion is to read, reread and know all the instructions inside out and not only know what you are doing but understand why you are doing it....
I don't have a razr, are they ready to be safely rooted?
Like the post above me says. Make sure u know how to do this. Rooting can help with battery life. Removal of extra apps. Custom Roms (which I don't know what the difference is between that and an alternate home replacement like adw launcher pro and 91 panda.)
I say root. (assuming there's a safe method and a way to go back to stock) Here's way. imagine you get an ota update. turns out the update messes up your phone BADLY (it's happened all too often) how do you go back? you can't you're stuck till the next update if any! and ota updates tend to break root methods. so now you're stuck. if you were rooted and you flashed a bad rom you just flash another better rom and you're good to go.
Yes, it's great to root (just as the others have stated).
I was rooted, but went back to stock, being there's virtually no ROMs out yet (although I do believe there's at least one). I'm also waiting for a more affirmative SBF. And from the looks of things the guys at XDA are getting really close to perfecting one.
So I'm gessing this time next month we should be getting better options for our Razrs.
