It's astonishing how much interest there is in what Apple will do next, and how much we cling to every indication of gadgets in the pipeline. Yesterday the blogs were abuzz with a vague hint from Apple board member Bill Campbell. In an hour-long talk to his employees at Intuit, he talked briefly about future products. And while he gave the standard line of not being at liberty to discuss Apple's forthcoming products, he did say he expects "a lot of things going on with the application of technology to really intimate things." Of course, everyone is interpreting that to mean an iWatch or some other wearable device is on its way.
