The primary factors for me using Linux right now, in order of importance:
1. Tiling Window Manager
2. Functional Declarative System-wide package manager (NixOS)
3. Cleanliness/simplicity (This is vague, but I have exactly the software I asked for and nothing else).
4. Configurability (I can adjust quirky in-the-middle software like my file manager, taskbar/clock, etc. No immutable one-size-fits-all UI/UX)
5. Repairability (Given time and patience, I can fix Linux problems. Fixing Windows is black magic, and I'm very often reminded, simultaneously, how much of an expert and how much of a novice I am on the CR/LF hand path.)
6. Auditability (Open source is more trustworthy, since source code can be freely audited by anyone at any time. Active free software projects accept security patches quickly and cleanly.)

Windows' design is diametrically opposed to all of these, and I can scarcely imagine a version that would allow a true tiling window manager (as opposed to the contemporary explorer.exe hacks).
Give me these features, and I will be truly impressed.
Do all that, then do the extinguish step, and you will really blow my mind.
