Some interesting points:

* 3x profit on the iPhone version ($7500 vs. $2500)

* android store piracy: 35%. iphone: 10%. (apparently it's easy to abuse the android 24-hour return policy)

* OP claims that eye candy is extremely important - "50% of the battle." Android doesn't require you to follow design guidelines, which might be why most of the apps 'look like crap'.

* Advice: "Find a broad niche and study your competitors. If you see room for substantial improvements, go for it. You'll make money."
