How do you count owners of phones willing to pay for apps? It's impossible to quantify that. As a business owner I need facts to base my decisions upon, not conjecture.
There was a report only a few days ago that said the average iPhone user only spends $40 a year on iTunes content for their iPhone. That includes music, films, tv, apps, books, etc. $40 a year that's all.
Where is Google's statement "we paid out xxx billion dollars to developers"?
And what do you mean by "only"? Most Android phones are $100 phones used as feature phones with not a single penny _ever_ paid on software or whatever.
