dual boot windows and linux is the best way. you will enver get better if you dont switch to linux, but sometimes you need to drop into windows for testing or whatver. if you found this forum then im sure you can find a windows key...
that was once true but now macos is not very stable, just expensive and more limited hardware choices. i dont think it makes sense anymore. if you just want to do some office work i guess its fine, and they still look good
