OK. I used to do that for IE but I haven't needed it in about a decade.

Some do. Not all. WINE is also impressively good now.

That, I certainly believe.

A whole bunch of reasons.
[1] No need for a Windows licence;
[2] Speed of startup;
[3] Much lower resource usage;
[4] Better integration with the host OS;
[5] No need to maintain a copy of Windows inside a VM with updates;
[6] No vulnerabilities in the host OS because there isn't one;
[7] Windows that freely mix with native windows, not in a single seamless plane for all of them.
I'm sure I could come up with more given more than a minute's thought. :-)
