Most non-technical users aren't going to remain interested long enough to try even a few desktop environments. The first one they use will leave a strong impression.
I would argue that having a choice between hundreds of DE's is a bad thing for the more casual user.
I'm not the person you replied to, but I use WSL regularly on the Windows machines I interact with (and have been since it launched via the Insiders program). As others mentioned, the key is keeping all of your files in the Windows filesystem (/mnt/c in WSL).
When I set up a new machine, the first thing I do after installing WSL is to remove all directories from my home folder on the WSL filesystem, then symlink the directories in my home folder on the Windows filesystem. This way I can avoid accidetally saving files within the WSL filesystem, but don't have to prepend all paths with /mnt/c/Users/me (almost all my work occurs within my home directory).
There were a couple of very minor hiccups in its early days, but for the last year I haven't had any issues with it at all and it certainly makes developing on Windows a whole lot more convenient.
Scenario: I want to position three separate windows so that I can see and use all of them on a single screen. When I launch the three application windows, they launch stacked on top of one another.
With window snapping, I can use keyboard shortcuts to quickly position each window and have all 3 windows be fully visible in their own distinct space, without having to remove my hands from the keyboard.
If window snapping 'doesn't provide any benefit', then there must be some alternate method that achieves what I've described above. What is this alternate method?
Are you suggesting that most offenders of what are typically seen as 'minor' or 'victimless' crimes are actually guilty of more serious crimes, but for whatever reason cannot be caught or prosecuted?
