I assume you would be doing things in VMs, right!? So what cross-OS issues?

IMO it's kind of weird to buy a frankly absurdly expensive laptop that locks you into using it's OS to then go and setup a bunch of virtualization to make your code/dependencies work when you can just run the OS you are virtualizing.

Why add layers of complexity when you can just run the OS you want?

Why use a VM when I can run things directly on the bare metal or in a docker container and not pay the virtualization overhead.

I'm not the original posted, but for me it's security and convenience reasons, mostly. I use Qubes OS which presents a very nice UI that makes using multiple VM's very seamless.
