...but iphone has 2.5% of the phone market, ~17% of the smartphone market and nothing on any of the consoles or handhelds when it comes to game sales (ie. above free) or revenues...

It's a growing market, and with Windows 7 Mobile coming later this year to feature Xbox Live, i'm sure Mobile gaming will take off dramatically.
