It’s cheap, really cheap. If you’re looking for a computer to send up to space on a balloon, then a Raspberry Pi is probably your cheapest component. It really doesn’t matter if it ends up in the sea. A few years ago the cheapest single board computer with the same capabilities was £100. Now it’s £5.
It isn’t a CPU with a GPU; it’s a GPU with a CPU. The graphics processor is what first boots up. It is responsible for configuring the hardware. Then it feeds the CPU a boot program and kicks it awake. That’s not a useful fact (unless you need to program the bare metal) but it’s very cool.
You cannot destroy it by typing anything on the keyboard. (You can by connecting other hardware to it, but you are not going to do that by accident and you run the same risk with any device.) If you hopelessly corrupt everything then you just take the SD card out and write a fresh install using your laptop, You’ll lose all your work, but that was backed-up, right? There’s no need to take it to the Geek Squad or buy your strange mate a beer. It costs nothing.
The SD card is the personality of the Raspberry Pi. If you swap SD cards then it’s the same as swapping computers. You can have one Raspberry Pi that serves as part of several different projects simply by having multiple SD cards. Similarly if a Raspberry Pi fails in service you can simply swap it out for a new one, plug in the SD card and everything will continue to work as if nothing had happened.
