I switch back and forth between my minimal modern desktop and the old version with a single key press. That said, I modified the modern screen to just have a terminal, IntelliJ, Github bash terminal, and a few other things and it is handy enough for quick launches of whatever I need. I don't really think much about the windows interface, just the few apps I use. Same as with OSX and Ubuntu: a moments thought to switch between a bash shell, IntelliJ, a web browser, but 99% of of what I am thinking about is what I do in individual apps.

The operating system is getting to be irrelevant in my world as an author and programmer.
