Those are all research projects at best, you can't buy any of them and you're not likely to be able to anytime soon.

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.
