I believe that in order to get the true iPhone experience a person must be a Mac user (like me). The integration with the entire Apple i-ecosystem is where the real magic happens. But as a stand-alone mobile device the Lumia looks like the best option available to me.
As I've said many times before (even to Microsoft), if they would support the open standards of CalDAV and CardDAV in WP8 I might be able to get the level of wireless sync with my Mac(s) I'm enjoying with the iPhone and I'd be trying a Lumia as we speak. Congrats on your new Lumia! I'm jealous!!
