It's pretty simple really. OSX used to be pretty nice, back then. Quick, very stable, lots of features etc. Then, the ioOSification started, and we're down to El Crapitan where the Mail.app barely works anymore. And that version is the last of a string of versions that were a lot worse as well... On the other side, Linux has improved in bits: + More stable graphic drivers; Intel & nVidia now have stable, working releases that don't require you to jump thru hoops to get the screen working, as it used to be back then... + Antialiased text. Seriously, it took a LONG time to get something working properly, all the time in linux.. + The other major thing that happened is ... Chrome. Chrome is spotless on linux nowadays, and personally, once I have an IDE, Chrome, and a few bits and pieces I don't need a lot more these days. I don't particularly think Linux has improved that much otherwise in terms of desktop usability; it's still the same mess as before on the desktop IMO, but at least the lower level bits have improved significantly...
