I watched the presentation by hu.ma.ne founder earlier in the week at TED in May, and I thought the device, the Ai Pin, was really different from what we have, read smartphones. What is the use of something without a screen? Then I remembered that people used to have Pagers, but even then, Pagers had a screen with the number to call back. But I digress. What really made me think was watching their launch video yesterday.
