That is true but Apple does seem to have a higher adoption rate with their physical products. iOS 4 killed support for the original iPhone and now iOS 5 is killing support for the iPhone 3G.

When the iPhone 5 comes out this fall I think by June of next year there will be enough penetration of iOS 5 that some apps will be able to put that requirement on it.

Heck if we're lucky iOS 6 will finally kill support for non-Retina displays.
