Don't get me started on the poor state of creative apps for Linux in general. GIMP is literally incapable of performing half the steps in my favorite photo editing workflows (features missing which were present in Photoshop 5.0 from 1998), and Audacity makes me angry more than any other piece of software I have ever used. Inkscape and Krita are decent, though.
1. None of the Ui packages out there in Linux is as good as macOS.
1.5. Gestures. Though I can live without one, I've grown accustomed to the slick motions.
2. Chinese input on Linux is unusable. It was so confusing I gave up setting it up on my (was) Ubuntu installation.
拼音键盘也可以用。
Try Fedora.
I can't even find a good calendar app for Linux.
What about the Lightning add-on for Thunderbird? Has that been of any use?
Other than that, I would be happy (likely happier) on linux vs. OSX or MacOS or whatever. I do not game, and living on the same basic bones as my servers is a win.
Of course, this may relate to how I compute and the software I use, but it doesn't quite line up with me. Nevertheless, I keep a fedora partition around for tinkering when the mood strikes.
One of the many reasons is desktop Linux has a terrible and well deserved reputation. Most people don't have any great yearning in their loins to switch operating systems so they would prefer to keep using what works for them. Desktop Linux would have to be a lot better than macOS to get people to even consider trying it out.
Lately, however, I've had to janitor my Mac more than my Linux system. Experienced more kernel panics with it as well.
