The Life of Pi: Ten Years of Raspberry Pi
I've posted about this a lot but I feel the need to evangelize it:The cleverest thing the Raspberry Pi can do that almost no-one uses is network boot.You don't need an SD card at all, you can setup your server such that you can change what OS a Pi boots into just by renaming a symlink.I have a bunch of Pis around my house that all network boot into specific tasks and it is a joy.
