I'm sure iPhone activations are pretty high too, but most likely, in all reality, they're not going to be as high as Android, since they're not matching the sheer volume of devices the numerous Android mfgs are cranking out.
Of course Apple shouldn't crank out as many devices as the Droid people, cause that just leads to fragmentation and instant obsolescence. But, IMHO Apple has failed to produce enough variety of devices to satisfy the number of customers that they should.
There is only 1 model of iPhone (old versions don't count). By contrast, even Apple produces 5 different notebooks (3 MacBook Pro, 2 MacBook Air). Apple should produce 3 different iPhone models. That should be sufficient. It's called choice, and customers like that, because one size really does not fit all. If there was more choice in the Apple camp, they'd see more activations - possibly more than all the Droids combined - now that would be awesome. I think Apple should make a 3", 3.5", and a 4" iPhone5. There, done.
