> It was a weird device, mostly a toy?

While I do agree it was/is weird, and it was/is hard to qualify, toy isn't the word I'd reach for. I find myself using it for some odd task once every few months. Cloning a keycard, temporarily standing in for a broken remote, etc. I'm glad I have it, but I was given it for free and I wouldn't pay for it.

> This new one is… yeah not sure. More of the same?

Not even. It's an ARM SBC in a weird case. The F0 was interesting because it had a bunch of oddball radio/IO peripherals; F1 doesn't seem to have anything comparable.
