The Apple rumor universe is speculating the iPhone, iPod and iPad maker wants to add another device to its arsenal in the form of an iWatch, tech websites say. A report cited by Business Insider says Apple has partnered with Intel to develop an iOS watch. Sources in Apple\'s supply chain have told Chinese blog site Tech163.com the watch would be Bluetooth-enabled and sport a 1.5-inch OLED display screen, CNET reported Thursday. Apple devices are no strangers to people\'s wrists; previous versions of the iPod Nano have done double-duty as watches with a number of manufacturers offering watchbands allowing the smallest iPod to be worn as a timepiece. But the iPod Nano was enlarged this year, too big to do duty as a watch, giving credence to rumors of a possible dedicated time-keeper from the Cupertino, Calif., company. The so-called smart wearable watch could reportedly debut in the first half of 2013 -- if rumors are to be believed.
