Linux powers the entire world. Billions if not tens of billions of devices. It doesn't "break all the time like a kit car". I switched my wife's desktop from Ubuntu to Debian about a year ago and I haven't heard a single complain. Not a single crash. She hardly reboots her computer. The thing is just rock solid and it needs to be: she works from home and she spends 8 hours+ on her (Linux) computer.
