The real problem of the android market is that.. is not a market!
It's a kind of "I wanna have apps things cos the iPhone has...", but their userbase are either people not interested in apps or very hard core open source guys who want everything for free, give them gcc and your source code and they are happy. What
paying for something? Are you barking mad?
I always measure the potential of a market not just in how many people there are in the market but in how many of those are potential customers.
The ratio iPhone/Android on that matter is simply embarrassing.
