Tivo is now offering the ability to order pizza from dominoes through the Tivo interface. Hm. I'd still have to navigate away from my shows to order. Could you at least provide picture-in-pizza?
I own a Tivo, and I like it. It is fast and does exactly what you ask. It also has the perk of permitting online show scheduling through a pretty reliable interface. What I don't like is that, despite my monthly fee, I am subjected to offers for additional services, so that I have effectively purchased and continue to subsidize a billboard in my home. I don't like it, but I am also pretty good at ignoring it. C'est la video.
