Linux - Will It Replace Your Favourite OS?

After so many years, Linux still trying to catch up with Windows.
How many of your guys here have dump windows completely?
Will you pick up the skills and knowledge for this OS?

Still using linux, for more than 5 years already. Basic use is ok.
Dump windows - no way.
Pick up skills and knowledge - unless fan/nerd/professional, else no reason to do so. I forgot most of what I've learnt in the past.

Windoze is not everyone's favorite.

I have used Mac, Linux and Ubuntu
