Care to post some facts behind your " is miles and light-years ahead of everyone else. Bar none." statement?
Go take a look at which devices support "mavericks" and come back and post your findings.
HINT: Many Mac Pro users were unhappy with the "line" at "2008 and newer"
Looking around my house, I have a SUN X4500 (Released July 2006) which runs Solaris 11.2 (Released April 2014). This alone exceeds Apple's "miles and light years" approach you listed by at least 2 years.
Windows PC's generally don't have arbitrary limits to which OS you can install (unlike Macs).
Next FUD please?
