So I don't have to have the overhead of a full Windows virtual machine draining my laptop battery and filling my SSD with updates I didn't ask for to run the few windows-only applications I use.

I make extensive use of alt-tab. I have yet to find a smooth way to switch between applications running inside a VM and applications running outside the VM.

I also haven't found a way to achieve acceptable video performance inside a VM, short of dedicating a graphics card and doing a full PCI-E passthrough.
