Probably true that phones will become good enough for most things. But at the same time, how many devices will the average person use? More or fewer? If it's more, then no matter what -- even if we don't know what those devices will be -- you want it to be easy to switch between them, which is the problem Continuum is solving. I think this is Google hedging its bets again and getting ready for whatever unpredictable thing happens next. They just assume it will include a proliferation of devices.
