None at all. My only caveat to that would be that I wouldn't pre-order it, unless you don't want it rooted or are okay waiting a couple weeks before having it rooted. Me personally, I won't be purchasing it until it's been out awhile. Hell, I may even wait to see how I like Sense 3.0 first as well, cause otherwise I might wait even longer for a working non-Sense rom or just upgrade to whatever the next "official" Google phone is.
