Don't underestimate the power games have to give a platform staying power. The prevailing sentiment in past discussions here has often been that games are interchangeable distractions, but there's a big portion of the public that is incredible passionate about their favourites and thus the platform on which they run. (We've been taken aback at the fan loyalty shown to some of our games, and this is stuff that's barely even troubled the lower reaches of the charts.)
Bingo. It is all very well to say "I and my business buddies only use 10 apps". Go have a look at a random teenager's iPhone and if they are not full of game apps I will eat my hat.
And yes there are a lot if kids with iPhones out there, either as full phones or without phone service. Where do you think all the previous generation devices are going?
In a family the app-store represents significant lock-in, both in collective $$ spent on apps and media, but also in the device hand me down chain. I bet there is a lot of pressure against one of the parents switching to an N9 all of a sudden.
Brand new smartphone users or company issues are (maybe) a different issue.
Games also tend to be the most portable and least "sticky" of all apps though. Most games are written with cross-platform engines or toolkits. If an app is a huge hit on iPhone you're likely to see it on Android not long after.
