Ah, I saw these on the NXP IoT truck that was touring around. What's the verdict? Got any ideas for what you're going to build with them?

So far I've been able to make my own bitmaps and display them, I'm still figuring out how to interface with the onboard sensors and switches.
The battery only lasts a couple of days, and less if you use the bluetooth frequently, so I'm working on an external battery pack.

I wonder if you can use low power programming like devices from TI and Cypress. I am looking at TI's and am impress how they have built the hardware.

PS. I am curious what you think of the use cases directions you may or others have taken.
