Google Fiber would be amazing, but even as I read that article I thought the same thing Tommy posted. Getting it to the outer boroughs will take years. Right now, I'm still waiting out and hoping the government denies the Time Warner/Comcast merger. They'll be orders of magnitude more powerful together, and stifle any competition in the area, including Google.
I wonder if we switched to Google Fiber if they'd have availability to YES, MSG, and SNY. I wouldn't want to give up my teams' channels. I guess I could just keep basic cable for them if need be.
