Now that this idea is validated, Apple will:

    A) acquire MINIMAL and hire Scott Wilson
    B) produce their own version
    C) not enter this market...

As a fashionable, designed product, it seems right up their alley, and Moore's Law says each version will get smaller. It's one of the few positions to carry a device, that people are used to (phone, watch, wallet, purse, keys, glasses, shoes, clothing, necklace, bracelet, ring).

BTW: How far off are facetime watches (aka Dick Tracy wristphone)? BTW: LG announced one in 2009 (multitouch, no video): http://www.foxnews.com/story/0,2933,477744,00.html and someone claims not a good idea http://dvice.com/archives/2010/07/wrist-speakerph.php
