I've been a Linux user since 1995 and run Windows + WSL2 on my desktop machines. It's not too deep and pretty similar to why so many folks were drawn to Macs; a no brains just works GUI with the ability to launch a terminal and do real work on a UNIX-like system.
I can use a single machine to do everything I need, without rebooting and without making sacrifices.
I can watch Netflix and play games, without needing to write a f'n shell script to fix the screen tearing present in the nvidia driver - or realizing a particular game has quirks or doesn't work in Proton, so I just have to throw up my arms and say "Well, I guess we just don't play that game".
I can pop open a terminal anytime and have access to a real Linux system, as opposed to the faux "uncanny valley linux" solutions like Cygwin and Git Bash that seem to work until they don't. And unlike a traditional VM there's no management involved; I open the terminal when I need it and close it when i'm done, just like a normal application.
If you want to remove a lot of unnecessary pain in your life, completely abandon the idea of mounting a host FS within a guest VM. Doubly so if they're different OS's/FS's and triply so if this a development VM.
Not quite. WSL2 dynamically uses resources as needed (`vmmem`), whereas a traditional VM requires allocating a fixed amount of RAM and CPU from the host machine.
I did. But I also have Windows machines, in which I use WSL2. Granted, I don't use GUI applications on them (or see much need to).
It's actually quite nice to have a "real" linux instance available on virtually any Windows machine. I believe Microsoft is targeting the "developer who uses a Mac" market share with WSL2 and I expect more and more to jump ship, as the experience is significantly better.
WSL2 uses it's own init system - only one kernel (plus a tiny initrd) is virtualized by hyper-v; each subsequent linux instance (distribution) is containerized. There's additional facilities that handle resource allocation dynamically vs the user specifying a static amount during VM creation.
These (and more) result in the end-user interacting with WSL2 the same way they would any normal application. To think of it as simply a VM isn't quite correct.
