I have a question and it would be nice to hear from some of the hard core Apple fans (assuming any actually know about this site). I'm wondering if it's worth replacing my Nexus One phone with an iPhone 4. I hear a lot of talk about how Apple's ridiculously priced MobileMe service offers more than what a free Gmail account offers on an Android phone. What exactly does Apple offer that Google doesn't? Apple's web site doesn't say. Also, what does iOS4 offer that the Android OS doesn't? Any Apple experts around that can go into detail?
