The Linux kernel surely takes over the world however Linux is nowhere to be seen on the pieczatki online where it matters most.

There's there's this still little known fact that Google wants to replace the Linux kernel with their own one. So, Android is not particularly bound to Linux since the kernel part of Android is anyone's to take.

What about supercomputers? They are great, right, except they are basically huge calculators, so it's not like a huge win in my book. Besides, *BSD could have been used there as well.

Then there's this fact that application/web servers only use Linux'es CPU/storage/networking capabilities and almost nothing else and then you'll get a pretty bleak picture of Linux dominance.
