For some time, I’ve been using a Fitbit One, which is a fancy pedometer that tracks my steps and sleep, and then syncs over the wifi to store my data in the cloud. In response, Fitbit will send me an email if I get close to my daily goal of 10,000 steps, which they evidently selected on the basis that biology likes round numbers.
Perhaps most importantly, the device itself will also randomly show encouraging messages on a little LED display, such as “U can do it,” or “Love ya,” or “Burn it.”
So, to recap: I carry around a small plastic box that talks to me. It loves me, but it spies on me and telepathically reports to a corporation on the other side of the country. Also, it tells me to burn things.
