Later this month, May 2010, Google is expected to announce Google TV. It will begin with a box using its android operating system (like windows, but open source) to be attached to your cable box or TV and allow internet activities via remote control. It could even replace your cable box.
Wow, if we could do other things during commercials, can you imagine how much we could get done. I vote for split screen. Hmmm. . . the possibilities are endless.
