It sure would be cool if this rumor turned out to be true:
Apple may be working on an “as-yet-undisclosed” feature that would let iOS 6 devices communicate via Bluetooth 4. One possible – and likely – use case is enabling an iPod Nano to control, and display messages and other data from, an iPhone or iPad. The Nano, of course, can be strapped to a user’s wrist and worn like a watch, thanks to third party accessories.
“This opens up many possibilities for the wrist set,” Seth Weintraub writes on 9to5Mac. “For instance, you could make a call on your iPad or Mac through the iPod nano watch as mentioned.” …
The concept of an iPod Nano watch, which Apple has endorsed semi-officially by releasing 17 new watch face designs last year, is a great start. Apple could polish it to a higher sheen by releasing its own branded smartwatch product. However, there’s no indication that such plans are in the works.
A networked iPod Nano plus iPhone would be a notable step forward for iOS users. Strapping the network to the wrist integrates mobile technology more deeply into everyday life. It may seem like a subtle shift, but not having to remove your phones from your pocket to complete certain tasks makes mobile tech noticeably more seamless. It’s also a step toward a future in which the line between people and their computers is further blurred.
