Had a relative switch to Linux recently. Lenovo IdeaPad computer running windows 10. The stuff was getting insanely slow and battery life was reduced ton the point that it was being a pain to use. Backed all the documents and data on a local instance of dufs running on home server and installed Linux Mint on it. Had minor issues regarding WiFi and Bluetooth. Solved the wifi one but bluetooth is still a bit unstable sometimes. Came back 1 week later and the user is delighted. Says that everything works 3 times faster than on windows and that battery lasts 3 times longer. They also went on themselves to look for open source alternatives to windows apps they were using and installed them. That's a win !
