I never said developers wouldn't develop apps for it. My point was that with 50% marketshare - developers wouldn't ignore it. IE - there's a benefit to good market share.
I can throw a small bit of info out there regarding development on the two platforms.
I developed exclusively on iOS until around 5 months ago. I ported one of my apps to Android, and its in the market.
I've got 6 apps in the iTunes App Store, and 2 in the Android Market.
The 2 android apps makes approx. 45% of the profit made from all my iOS apps. Based on this, (for me) Android is a more profitable platform. This wasn't the case for the first month or two, however recently I've seen a dramatic increase in Android app purchases.
My stats are also not warped by advertorials as I dont pay for any advertising for any of my apps, and dont promote one platform over the other, its simply worked out that the Android apps have had a decent number of downloads.
Obviously you cant read too much into this....it would be interesting to see other multi-platform developers statistics however as it would help grasp a general idea of platform usage trends.
