Why would you use this compared to the M5 stack which kind of does the same thing? This just looks like it's packaged in a "cuter" sense.
For me the fact that it has NFC built-in makes it perfect for my usecase. I looked at the M5 and friends but having to add an extra add-on box with a cable was a nonstarter for me.
If it takes cute packaging to get people into it, so be it. This seems like a great project. The more the merrier
