Like the others said, it depends on the details. For me, the deal breaker is the Tivo.
In addition, you will have free use of a digital TV recording service (similar to TiVo) that
If it's not a Tivo, I don't want it, even if it is free. I have tried to use the DirecTV version of their HD DVR and it is a piece of crap.
The other "minor details" are the price, quality and reliability. Right now I don't pay over $100 for HD DirecTV plus Vonage. Since I get my cable modem paid for by work, a potentially slower version would be of no interest.
