Considering a large percentage of Facebook users are from the Boomer generation, and the Boomers are not all that tech crazy towards gizmos and gadgets like this watch, I think this will be a failure. Boomers might use Facebook because there is no alternative that will actually attract enough of their family and friends, but they are are not stupid about how slimy Facebook is. I'm pretty sure they are smart enough not to buy anything from Zucker the Turd. I don't think Facebook has enough members who would really be interested in this kind of device.
