“Wearables” is a newer buzz word that refers to electronics that you can wear rather than carry. Digital watches are technically in this class but people usually use the term for something more obscure.
Like a shirt that has a display showing how many email are in your inbox. Or a hat that displays the subject of recent tweets or emails.
I think there will be something genuinely useful that will come forward so I’m working on it. This could take a while. :)
