The iPhone isn't marketed to the crackberry/windows mobile crowd, i.e. real estate agents. I don't see why everyone finds exchange connectivity on it to be so damn important anyway since there are a bunch of other capabilities it doesn't have that business users seem to clamor for, i.e. being able to edit documents on the move (though Excel on a 3" screen is probably not something I'd want to use). Honestly this iPhone/exchange thing is just a bunch of pundits looking for more pageviews, because the rest of the world that's actually going out and buying iphones doesn't seem to care about Microsoft that much in the first place.
