I think the biggest miss Google had was with Google Wave. It was way ahead of its time, and absolutely crashed and burned at launch because of the invite-only model.

I bought a Google OnHub router, which was amazing. It was marketed as the most “future-proof” router at the time. Then Google made Google WiFi mesh routers around a year later, and OnHub was never marketed or mentioned again. Now, in addition to my already concerning privacy issues around Google services, I don’t trust that they will release quality, supported products.
