Wearable computing, in general, is unlikely to be as successful as a tablet with a great capacitive, finger-friendly touchscreen and a UI designed for fingers.

The modern tablet is a true breakthrough. Wearables are potential new market, and there is some excitement around the fact that both Google and Apple will enter that market soon. But wearables are far from a sure thing.

For one thing, Google Glass has a voice user interface. Google's speech recognition is the best there is, but on alternate days it still veers from astounding to laughable.

The most compelling application, face recognition, has a high creepiness factor, and Google probably won't touch it even though I would be first in line to buy if I could pick everyone in my contact list out of a crowd.
