Take a look at the two lists (below) for yourself (original PDF here). It does practically nothing to sway me. More than a few of those paid apps are published by Apple (e.g., Pages, iMovie) and many others like Wheel of Fortune (both platforms) and Clash of Clans (iOS platform only) are not exactly critical.
While developers in the past have favored iOS, I don't know how true that is universally today. A recent article in The Guardian makes the case thatAndroid fragmentation makes it more difficult for developers on that platform.
But I think it's a more complex argument now in light of the fact that Android momentum is unmistakable. Again, the upshot for me is that I get what I need from Android now.
Hardware: A quick word about hardware. Google has achieved hardware parity -- certainly on tablets. Though the first-generation Nexus 7 had issues with lag (scrolling) and frame rates,that's not the case with the second-generation Nexus 7 and the Nexus 10 (both run Android 4.3).
In fact, Google leapfrogged the iPad Mini with the newest Nexus 7 (in some respects): better screen, faster processor.
And the Nexus 10 (which I use a lot) is thinner and lighter, and the weight is distributed better than it is in the iPad 4. And the Nexus 10 is plenty fast too, with a higher-resolution screen than the iPad has.
Of course, all of this could change in the next few months when Apple rolls out iOS 7 and an expected high-resolution iPad Mini and a highly anticipated thinner, lighter iPad 5.
But for now, I'm an agnostic.
