This is the question asked by Chris Lanier on his blog. The responses were all over the place. I am thinking about it when Vista comes out. I think the real reason to upgrade is CableCard support, and I am curious to see how well Microsoft implements that support. How will I be able to watch HDTV? If I am able to watch and record HDTV from either cable or satellite, then I will be very interested. By all accounts you will be able to do this.
