Hey, are you a DIRECTV customer? Do you own an Android tablet? Then I might have some good news for you: DIRECTV just released an app for tablets, and it does all sorts of awesome stuff. You can watch live TV (only some channels!) on your home network, and some (read: fewer) channels from anywhere with an internet connection. You can browse listings, set and control your DVR, and even change the channel on your set top box - this really is an app absolutely busting at the seams with great features.
However, DIRECTV has thought it wise to make this app unavailable to 7" tablets (at least for now).
