True true! I am stuck to Windows at work, while we SSH into development Linux machines. Windows terminal and WSL keep me from going insane. All I need to do is just F11 the terminal, make it fullscreen and forget ever that I am on Windows.
With Mac OS I still like the Mac terminal more than the Windows terminal and just SSH into Linux boxes.
Still, for me, nothing beats a Linux desktop with i3wm on it.
You can run i3 via WSL if you use an alternate X server like X410 or vcxsrv instead of the built-in wayland RDP bridge thing. vcxsrv is a bit nicer, since it lets you run the X display in fullscreen mode.
I don't know anything about WSL, but if it has a wayland server like you say and if 22SAS wants to use i3, they could try sway with the wayland backend.
I have heard of it but never used it. I'd try it out on my personal machines. Work machines are Windows thin clients, since IT doesn't want to support Macs and the Linux teams are absolutely only concerned with dev and prod Linux machines. Plus being in HFT, the machines are all tightly locked down, couldn't even install WSL and Windows Terminal on my own.
Sadly you do need both a mosh client and a server installed. But you might get tremendous productivity benefits which might make it worth auditing it (maybe worth talking to your boss/customer).
Mosh is lovely, but keep in mind that you can't use agent forwarding, nor use it in pipes. On the other hand, if you're stuck on dodgy Wi-Fi or just about any mobile link, or you want to close your laptop and resume your session elsewhere, it's an absolute godsend.
Mosh backed up with either tmux or screen is handy indeed.
