I should say the same to you.
Linux is failing. The places its winning is in appliances/embedded, in servers (big footprint, my company uses them) and other "niche".

Linux is failing where the spotlight is: Mainstream.

Everybody knows about Windows, they know about Android, some know about iOS and OSX. They (public) don't really know of Linux's existence.

Yes, this is a good thing... but its also a bad thing.
It is perfectly possible to have Linux presence/dominance in the niche as well as the mainstream. Its because Linux is adaptable to many types of tasks, that's what we mean when we say "it is powerful".

And the point I made earlier is still true today, MeeGo was supposed to be backed by a dozen big corporations and was going to bring Linux into the mainstream by Penetrating it, Standardizing it, Bringing in AAA Developer Incentive and creating a convenient Store for all.
