I really like the idea of Google TV. It’s got lots of potential which you can learn more about here.
The only thing that is missing is….
1. True HD watching experience.
2. Lack of 5.1 audio on home theatre
3. Does not use capabilities offered through my provider, AT&T such as total home DVR.
Don’t forget, Microsoft makes the middleware for AT&T’s U-verse. I believe they could keep the best of U-verse, and layer it with BIng on top, giving you the same offering as Google TV.
