I'm halfway through switching over from an ancient windows XP to Ubuntu. I've had loads of help with all the technical stuff, but all the new stuff that needs learning and habits that need changing and stuff not working yet that has to be done without is mind boggling. Not that I have any choice since the old computer has broken down almost completely, but still something I've been meaning to do for many years and way scarier than can be in any way communicated given how many things I'm completely dependent on it for.
