That's an important point. Android is a complete non-starter in the non-phone MP3 device market, and the Android tablets are just starting out and have little market penetration. When comparing all iOS devices to all Android devices, instead of just phones to phones, iOS numbers definitely get a big boost.

My son has a iPod touch 8G, and I have an iPhone 3G (also 8G). The iPod touch is by far the more performant of the two - it's almost like a different device. I don't know what goes on in the guts of my iPhone, but I find it surprising on how much computing power it takes to run the cell-phone side of things.
