YOu can also copy programs off to a VCR in real time if you absolutely still have to have something on tape.
It's a much better TV guide than anything printed as well. A search for CSI found no fewer than 16 different channels and showtimes over the course of a week, most of which I never knew about. Even the original show is on six times on three different channels.
The keyword search feature alone finds all sorts of stuff I would never know to look for. A search for "Tiger" found all sorts of neat stuff - but as can be expected, most of it was on the Golf channel.
It updates the memorized programming every few days or so - so it isn't always up to date if there is any breaking news that pre-empts stuff. For example the two CSI shows I thought it had recorded both turned out to be parts of ongoing coverage from the Vatican instead. And in another case it caught only part of a movie that had been delayed. Still, a hell of a lot better than VCR+ if you remember that.
OK, I admit it, I really bought it because Blake had one.
