That's my main concern about WATCH. The apps for it don't exist yet, and it's possible they never will.

A pocket computer with a touch screen is a general computing device. But there's very little anyone can do with a watch-sized consumer product - especially if it lacks extras like really good fitness and health hardware.

I totally get the potential of haptic wearables, but WATCH seems like a 0.5 product with some eccentric design choices that's still on the wrong side of industrial practicality - not like a product with enough awesome to appeal outside the fan/early adopter crowd.

I'm sure Cook & Co are thinking of it as a beach head, not a finished battle. But even so - it has to entice a critical mass of consumers or there will be no follow-ups.
