Well, so Google says. That seems a convenient way to get people off their backs for having both. Google TV runs on Android, not Chrome. Google TV isn't a touchscreen. The reality is, Google has two different product teams and had no intention of telling either one to give up on their goals. And with Apple pushing both MacOS and iOS, it has no immediate need to do so, either.
Google wants ChromeOS to eventually replace Android. It's cloud vs native, not Touch vs Keyboard and Mouse, and until cloud based becomes acceptable everywhere, which is what Google is betting on, they will continue to work on Android.
