Scrolling is woeful. At least on mine, When scrolling through a long picture folder or music list I almost have to turn away due to how jerky it is. And the switching between desktops should be so much better. Also takes a while to load so many things unlike on the iphone where you tap and it just opens up what you tapped immediately. Someone mentioned that the rotation distracts from the fact that it is loading up but if the N900 had the same feature it would often have to rotate a 100 times just (slight exaggeration ofcourse) just to open up what you have selected, or freeze up for five seconds in the middle of the rotating screen.
