I love Linux. I mean take this example of an old netbook I got on Freegle. The hard drive was toast so I swapped in one from another netbook with a smaller screen. This already had Ubuntu on it, but everything just worked first time, nothing more to do. I connected it to the network and it asked if I wanted to upgrade to Ubuntu 14.10 and update software. Sure, go ahead. So it did. No worries.
