My wife informed me of this one. Time Warner Cable has a free app that you can download and watch HD channels using wifi. Right now 31 channels are available in my area with more being promised.
I checked it out and it does have some issues streaming if you are in a remote part of your home, you know, where modem strength might be a bit weak. But if you want to watch something in a room with no TV, hey, it just does the job. Check it out it is free. Time Warner Cable subscribers only.
