Yeah. But docker is a just a container. Not only do I sometimes develop things in console ( for services) but also develop tools in DE (such as PyCharm, IDEA, QT creator, android studio).

What's the difference if you install GNU/Linux on a Mac, will you regret it?

Yeah docker won't get you GUI software like QT Creator to use those on my mac (when I had a mac) I used a regular virutal box vm with a full xubuntu install.

check out https://hub.docker.com/r/zachdeibert/qt-creator/

desktop apps in docker are just a matter of mounting relevant drivers and files in the container

Okay. So basically this guy uses docker to set up a X11 server with qt creator and other development environment in a server. Meaning while, the user can use a local X11 client to connect to the X11 server which do the real computing.

But this highly depends on the quality of Internet. Every PC can do it with a X11 client.

This is a good try, but not very practical.

with a little bit of tweaking you can run desktop apps in containers. check out Jessie Frazelle's dockerfiles: https://github.com/jessfraz/dockerfiles

edit: to answer your question: you'll probably encounter bugs and glitches, as the hardware may not be fully supported. i've heard of issues with wifi, bluetooth, power management, etc.
