There appears to be a lot of discussion about market penetration of the two operating systems. This is a separate discussion. The author is comparing the new iOS functionality to that present on ICS.
People continue (and chances are will continue) to make the market penetration argument for the following reason:
If the feature exists, but no one can use it, does it really exist?
Claiming that Android had a feature first doesn't mean anything to the consumer who can't get that feature on their device. Compared to iOS where announced features show up on most devices and on every new device that you buy in the store the very same day.
