I got it for the discounted AppleTV. $105 including 3 months of service for a $149 unit was a no brainer.
The service itself though hasn't been very good. Lots of streaming errors. No single-sign-on. Most of the apps that channels use for on-demand streaming don't have DirecT Now listed as a provider, so you can't use them. The only one that I've found that works is ESPN.
I really just wanted NBC, CBS, ABC, and FOX streaming, but it only has one of those (ABC) that both works and supports on-demand. It's pretty damn disappointing. At the end of the 3 months if it's still the same I am cancelling.
