Uverse has been available to me for a few months now but I haven't switched and have no interest in doing so.  While Uverse has a couple of channels that I would like that CV doesn't offer (HDNet, NFL) they also don't carry channels that CV does that are a must for me (MSG, Hartford Locals).  The biggest reason I don't like Uverse is the fact that you can only get 1 HD channel at a time in your house.  I have two HDTV's and with CV it's common that I will be recording two HD channels on the HD-DVR downstairs and watching a different HD show upstairs.  You can't do that with Uverse.  The other thing is AT&T's internet speed is a joke.  In two or three years Uverse might improve but for now it not a consideration to me.
While I welcome the competition, I think we will benefit even more from the competition Verizon FIOS is giving them in NY & NJ and from Satellite HD additions.
