When you swipe your finger across the homescreens on the N900, the transition follows your finger and the background and widget layers move at a different rate. And it does this very smoothly. When you swipe your finger on a Symbian^3 homescreen, it waits until your swipe is complete before the transition occurs. Although the support and applications are lacking, Maemo 5 just has more potential as an OS than Symbian^3, IMO. Symbian^3 is a nice improvement over S60v5, but it's still the old Symbian running Avkon. If anything, I would wait for Symbian^4 because of its compatibility breaks. - mp
