I wouldn't call the iOS clunky, just in comparison to be BB10. It's the same issue BB had in the past with BBOS 5,6, 7 was better (they felt clunky and looked clunky compared ot android and iOS) but BB10 has now surpassed iOS and android in feel and flow. Well literally BB10 is called flow. I still think iOS would be easier for someones grandmother to use, since, it's just push button based where as BB10 is gestures based (think minority report Tom Cruise for people who don't get the difference between gestures and push button). iOS and Android definitely feel dated and antiquated when up against BB10. Once BB10 app store grows, for myself, I wouldn't have any compelling reason to go back to an iPhone. BB10 is that good.
