Sorry, I couldn't resist.

1) "Solaris running on more processors"? Think of Beowulf clusters.
   Strangely enough, people running them choose Linux as the kernel.
2) "QNX is real-time", true. Linux is not. Please don't compare apples with
   oranges.
3) "Windows has more apps"? True. Is it a kernel property of any kind? No.
4) "MacOS has better color and font management" this is funny as it speaks
   for itself. I'd also add "MacOS is usually housed in a better-looking
   case". Luckily enough, under Linux color and font management is NOT a
   kernel job. No more than the external design of the case, I mean.

And I really hope Linux will *never* be exactly the same as Solaris,
technically.
