I was more saying that because of the point that yes, there's a lot of Android devices out there, but a lot of them are quite lacking in terms of power - therefore, unlike with iOS, it's possible that a device (even a new one) may not be powerful enough to run a certain app. However, unless the power requirements limit you to the top-of-the-line devices, this should still be a much larger market than iOS.
(Then there's Windows Phone and Blackberry, but then, not that many people have either of those, especially the latter.)
