I knew someone at my old makerspace who was using it for a final thesis project several years back, when it was just out a year or so.

He was a very capable C# programmer, I think this was the reason for picking it. But over the course of the project he became really bitter and his opinion dropped considerably. Apparently many things that are super easy to do on raspbian were impossible or super hard on Windows IoT. Not regular computing stuff, but integrating with hardware. GPIO, I2C, that kind of stuff.. The kind of stuff that's Bread & Butter for IoT in other words ;)

I can't validate this as I've never really used it myself other than booting it once. But I valued his opinion highly.

Yep, you'd need to write a device driver for all the hardware if Microsoft hasn't done it for you.

I would not use Windows on a Pi, it can be done, but makes no sense to me.
