NEW YORK -- Apple ( AAPL) CEO Tim Cook told a conference Tuesday that the iPod and iPhone maker was "incredibly interested" in wearable computers. "It's an area where it's ripe for exploration. It could be a profound area," Cook said at a conference sponsored by the All Things Digital technology blog. "It's ripe for us all getting excited about. I think there will be tons of companies playing in this," Cook said. Rumors have circulated this year that Apple is developing and testing a "smart watch" type of device which will run on Apple's iOS software. Cook didn't say at the conference whether Apple was working on any wearable products.
