This is a super fun gizmo, it's discord channel is, uh, not great.
One cool thing is that you can talk to it serially. I pretty quickly had it organized with an IoT temperature sensor so that it could send commands to my ceiling fan given the temperature in my office.
I have also used it to capture the NFC code on a hotel card key so that I could still get into my room even after my key was inevitably "damaged" by nearness to other fields.
Some parts of it are silly, like the Tomagachi type game with the dolphin. Doesn't add value for me, but I can see how it might be something for someone.
There is also growing awareness with agencies about its flexibility, some apocryphal stories of them being confiscated by TSA checkpoints have come in.
Writing your own apps for them has a fairly high learning curve.
