A recent survey of 600 smartphone users showed that 73% of iPhone owners used their iPhones primarily for person reasons. Now compare that to the 59% of other smartphone users to use their smartphone primarily for personal reasons. Perhaps this finally proves that users of Apple products really do have more fun.
Now I could go on and debate if it is wrong or not to use a business phone for personal use, but I have to warn you I am biased. I just bought an iPhone for my work phone a couple weeks ago. Am I using it for business or pleasure? I don't think I should answer that question.
