Why are you looking for a wearable computer? Browsing while exercising?
The idea of being able to work anywhere, I mean to do serious work not the kind you can do on a phone or on a tablet, has some appeal.
Think about being able to work (productive work) sitting outside in a park, or just lying in bed. It could also be helpful to people with disabilities.
I'm not sure it would be practical, but how will we know until we actually try?
Yes, you may say that you can do that with an ultraportable, but not in comfortable positions generally. That means less hours of real productivity.
One thing I know is that so far serious work most of the time implies a real usable, even high quality, keyboard. Not a virtual keyboard.
And a real, serious, quality pointing device. A finger touching glass is not even close.
I don't think speech recognition, even if it was 100% accurate, would be satisfying. It's too tiring and inefficient, and I'm not even talking about confidentiality issues. Speech recognition is a bad good idea, like the idea to be able to touch your monitor instead of using a mouse. It's good in some cases, but it still doesn't beat a good keyboard and a mouse (unless you are a noob at both).
So until we are able to connect a computer directly to our nerves and neurons, wearable keyboards, displays and pointing devices seem to have a future.
