I've owned 2 different iPod Touches over the past 2-3 years, and I've owned an Android phone for a year and a half. I've bought apps for both platforms.
The plural of anecdote is not data. There are apps worth paying for on Android. But for whatever reason -- maybe it's quality, maybe it's customer sentiment -- iOS users tend to spend more money in the App Store than Android users spend in the Market.
and I've also never purchased an app on Android.
So either we're both under the bridge, or you've mis-labeled the troll. (Look in the mirror.)
