I'll be interested to see how wholeheartedly they pursue those ventures, and how many turn into real markets, but yes there are definitely potential counter-examples, I'm sure you could think of some for Apple too, like the now seemingly inevitable smart watch. I don't expect something with the impact of the ipod/iphone/google search from either of them now though, and glass to me is completely underwhelming because I have no interest in walking around with a camera on my person linked to google. Ubiquitous networked computing is coming though, and you could say that's a forerunner of it even if it doesn't pan out.

However Google's search and advertising business (which funds all the rest) has definitely been more focussed on revenue for a while, and Apple has that same feel to me (as a customer and developer) of a company which has peaked and been taken over by those more interested in generating cash than ideas.

Completely understand why you might not agree though.
