Are you using the free version or a paid option? Because I find the non-free options to be vastly more expensive than hosting options elsewhere. They provide a valuable service in terms of taking administration issues out of the picture and letting you just focus on developing your app. But my feeling is this is not targeted at hackers who are surviving on rice and beans but rather those who are more likely to have well-paying day jobs. Not that there's anything wrong with that - it's a good business model - but since I'm in the rice and beans category at the moment, I'm not in their league I'm afraid.
