While we're on the subject of gadgets, I just an HD Tivo. For the past year or so, we've had two boxes - one for Tivo and one for HD. This box brings it all together - Directv is finally offering this at a realistic price.
Problem is they are moving to MPEG4 and HDTivo doesn't support that -- or vice versa. It will be interesting to see what happens with everyone who bought HD Tivos. I'm guessing they'll continue to provide feeds that work and then offer to upgrade everyone. I'm no so certain their box will do what Tivo does though - sure it'll record shows -- but it won't be a Tivo.
