I really enjoy working with the Mac and am very productive with it, but this would most likely represent the end of the road for me to use it in a professional capacity.

One of the tools that I require to do my job, a development environment for an ERP system, is a Windows application. It's a closed-source commercial application. The likelihood of it getting ported to MacOS is zero, so it's always going to require me to run Windows in some capacity in order to use it.

There are three ways I see this tool working on an ARM-based Mac:

* MacOS emulates enough of the Intel instruction set that VMware still runs. And doesn't kill it in the next version like they did the PowerPC emulation after the Intel switch.

* VMware runs but gives me a virtual ARM CPU which runs an ARM version of Windows which emulates an Intel CPU. I'm not sure what the ARM virtualization story is, so this may not even be a thing,

* I keep an Intel machine under my desk and use RDP. This is somewhat cheating and it's unlikely that work would be willing to pay for two machines.

On the flip side, Windows 10 seems to be getting really good, so switching actually wouldn't be that bad. WSL will basically give me all of the command-line tools that I need, Hyper-V can meet my virtualization needs (though I won't require it like I do on the Mac), and all of my other tools are available on Windows.
