One of the most interesting things I’ve experienced while using the Apple Watch over the past two and a half months is the growing consciousness that I am now wearing several machines that are capable of talking to each other.

This was illustrated one morning when I was in the New York City subway, deep underground. There—far from any cellular signal or internet connection—I used my Apple Watch to wirelessly change the podcast that was playing on my iPhone, which was being wirelessly transmitted to a pair of Bluetooth earphones. I had my own invisible, personal network, off the grid.

This phenomenon—some are calling it the “personal cloud” or “personal mesh”—is one of the most important changes that will come out of the rise of wearable devices, such as the Apple Watch.

Will the idea of portable clouds evolve? Imagine traveling with a group of friends with a local cloud of shared maps, links, photos, texts, etc., all accessed as part of a local, perhaps temporary cloud.

Great food for thought.
