And the winna . . .
Okay, people, double-check the math and we'll declare a winner. Let's say, by January 10. That way it's super fair. OS X (10!) and Windows 10. Or maybe we should use Windows 8.1 to be extra fair. Problem is that 10-8.1=1.9, and that's not an integer. We'd have to rectify that with the CVEs which are integers only IIRC.
Gimme a minnit to get my popcorn. This is gonna be good! :)
I'm predicting that Windows 8.1 will tie with OS X and Windows 10 will break the tie. Final score: 1.9. But, come on. Was there really any doubt?
