It's not the kernel that the source of the problem. It's the desktop. Changing the kernel away from Linux is not going to do diddly squat if we are still saddled with KDE or Mate or Cinnamon or Gnome or Xfce or blasted Unity.
Linux has not won the desktop because the the Linux desktops all blow. I use Xfce, I like it the best because it stays out of my way more than the rest.
Why do so many hackers prefer Mac? It's not for the overpriced hardware. Is it because the suspend works so well? It cannot be for the GUI because the OS X GUI really blows.
Then there's Windows 8, an utterly unusable abomination...
