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.
It really bugged me that one of its selling features was the ability to open doors and gates and such, but it refused to open my garage door (which has an '80s pre-rolling-codes old fashioned signal, but it's within the standard bands) because of some FCC technicality. I heard there was some third-party firmware that enabled such things, but it made me wary that it might be illegal to install...
only to find out nfc-b would never come
meh
