I have Windows only audio and 3d software. I ended up with a windows VM with GPU passthrough on Linux. It sits on its own m2 drive for the rare occasion I need to dual boot. So Windows has been become legacy software for me. (IClone and CC).

And Steam Deck is there.

But I think the desktop interface is legacy for anyone under the age of 25, I get a kick out of watching them navigate a desktop.
