This is awesome, though I wish they would have used a chip with Bluetooth or WiFi.

  That would eat through the batteries. Which means you likely need a different battery, which means more bulk, which ultimately changes the entire value proposition, and now you may have well buy a cheap android phone. This thing, while worn requires zero power. You only require power to rotate the image.

    As someone who was working on a Wi-Fi connected e-ink display, you’d power down once you updated the display obviously.

    Not really, provided the duty cycle is low enough. Espressif chips can be set up so that they boot, run some code and then shut down with a timer (deepsleep). You can stretch the battery quite far that way. I did this to monitor temperature in an outdoor pool. Omega sell plenty of WiFi connected industrial sensors (with small batteries) that are specced to run for a year or so before a recharge. Usually they report measurements on the order of minutes. I also have a Bluetooth HRM which I've used for years (probably days of use, cumulatively). I've maybe changed the battery once.
