The numbers don't speak for themselves: how many 2.3 users are actively purchasing apps/services? Are people buying a $60 Android phone for use on a prepaid plan likely to purchase/install your particular app? The economics may favor dropping 2.3 support regardless of the overall install base. Then again, for certain situations, they may not. Of the two wildly different apps I work on, one has 40% of users on 2.3, and the other has 10%.
