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.
I've wanted a device that could for eg spoof itself as a USB device (I needed to boot linux and thought a computer instead of a pendrive would be cool) and went down a rabbit hole of the hardware requirements. I doubt the flipper (zero)'s processor could do that kind of work tbh.
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.
