* Would miss too many amazingly useful utilities like arsclip.
* Easier to patch into my home network, which is NTFS-based.
* Employer is now wedded to Microsoft and Azure, so having Powershell and native access to NTFS AD on my native desktop is proving more useful.
* I actually like the Windows interface, even with the Control Panel and other system utilities caught in a weird split between Windows XP and WIndows 10 UIs.
* Some things, like certificate management and hosting a personal database, I do in Ubuntu or Debian as a VirtualBox guest under Windows.
* Wife uses Windows on her laptop. She doesn't know it, but it's actually running as a VM on Debian, very stable, and can easily take her Windows to a new machine.
* [I keep coming back to add items to this list] Remote Desktop Services have improved vastly, and I can manage remote servers or 12 year old client machines at a remote site with equal ease. (XP/7-era machines got a second life when I converted Windows OS disk to SSD). Also find screen sharing via 3rd party VNC (TightVNC) useful.
* The keystrokes have become second-nature. Try as I might, I can never get fully comfortable on a Mac OS desktop. Now get off my lawn.
