A new user survey published by Hunch shows that Android users are more conservative and more pessimistic than iPhone users. The survey asked over 15,000 users a wide range of questions, but also then cross-referenced these against the respondents' choice of mobile OS. In a finding that won't surprise many developers, Android users were 29 percent more likely to prefer saving their money, while iPhone users were 26 percent more likely to prefer spending their money.
