Well, I decided to do it and have ordered U-Verse (to replace Comcast - providing the install goes OK). The install is scheduled for next Wednesday (the 11th) starting in the 8-10 am time frame.
I chose the package and options and then scheduled the install, all online. I received a confirmation email with both an order and account number. To this point I have heard nothing further.
Main reason for switch is both the additional HD channels (just a few that I would really like to have). And the fact that I should end up saving $30-$40 a month. I ordered both TV and Internet service. Phone service is, apparently not available here just yet so they'll give me U-Verse pricing on my regular phone service until it does become available. This is where the savings come from.
Presently the TV plus Internet is basically a wash, primarily because of the need for an additional two boxes. If necessary I can save an additional $25 a month by dropping the movie package (20) and the extra HD channel package (5). This latter package includes MGM and Smithsonian, both of which I would like to have. (The HBO/Cinemax package costs $24 a month - which I did not order). All premium channels include east and west feeds plus multiple HD channels.
Since U-Verse offers a 30 day money back guarantee I'll keep the Comcast service for at least a little while until I am really sure.
Two things that will cause me to say no is a lack of bandwidth so I can only get a single HD stream or wiring on the outside walls of the house!
I'll let you know of my experience!
