Me too, at the moment the only real-time tv I watch is the news, and even that's not very often. Sometimes I'll manage to catch an F1 or IndyCar race, if I manage to remember, and be in my house, and not busy. TV Shows I get via bittorrent and watch when I get around to it, I'm about a year behind most series now but have plenty of HD space to keep grabbing new episodes as they come out :). My HTPC is built to look just like a standard DVD player (I repurposed the case), has a remote and boots straight into XBMC, so even the kids can operate it (my porn is not in XBMC, it's deeply buried in a nested folder structure elsewhere!)
Though this model isn't entirely new, a previous work colleague of mine only watched TV shows when they were released on DVD.
