Why Apple thought a wrist-borne I/O device for an iPhone would be a big seller is beyond me. A wrist-borne stand-along computer with a touch-screen interface might be a fun product that lots of technophiles would have wanted and could have generated significant sales, but the iWatch isn’t it.
Make that stand-alone, rather than “stand-along”.

Steve Jobs was against the idea. The Gay Boy Wonder wanted to make is mark.
