I bought one of those last year, I love it! Aside from a rudimentary DVR for Antenna channels, it’s a nice little Android box as well.
At the time, they had a $40 Coupon, which I learned about in these forums. Great purchase and I’m still using this. As an aside, it’s also great for the times when you just want to watch TV, as the guide is excellent and switching is Instant.
You can load the Tablo app onto it as well, and then have access to both your onboard DVR and the Tablo live-plus-dvr. Excellent combination.
