Can't say for sure but....
Business apps? Bleh Games? Mines anyone? It really boils down to people going with their comfort zone so....
My parents who ignoring computers since my first Nt4 MCSE until I installed Ubuntu and Open Office on this old Gateway my father got a 'deal' on now run their rental business completely from Linux. They still think their 3gs iPhones are sufficient for internet browsing so this little box Linux has happily run completely without updates for two years now running the a small business with people who couldn't care less about open source/close source.
I would geek out talking about how awesome the new Unity desktop is, how my entire household runs Linux for everything including our desktops and my wife's laptop, etc etc. What this little experiment really shows is that people that don't know better, know Linux is without comparison for stability, usability, and most of all, value.
