We have it and we love it. The turnaround time for movies is generally pretty quick (and we live in a rural area), and we don't have to worry about late fees.
We don't download to the TV, though. We do watch movies on our laptop occasionally, but the problem with that is that it stops at least twice or three times for five minutes or so because "connection time has slowed" and it needs to "adjust playback" or some such. But if you have a faster connection, maybe that's not an issue?
