Depends what you define by a smartphone. iPhone strives to do thins to you by guessing and providing you with your needs as best as it can. It works, doesn't freeze, provides seamless integration of many functions and is idiot-proof. IPhone is a smartphone. N9 is for me a dumbphone. N9 call quality is nice and threaded SMS and IM and Skype in one place is unique. But otherwise it fails, so I use N9 as my dumbphone , pretty and nice to hold. iPhone doesn't require tweaks or mods or whatever to work properly. N900 and N9 do. N900 and N9 not very smart.
