Demonstrated on Nokia's current flagship, the Nokia N8, the new UI looks much more compact with a thinner status bar looking similar to the one on Android. The call menu on the bottom has also become much slimmer, while in the middle, widgets no longer look cramped. However minor this update might seem, it gives a refreshed contemporary look to Symbian^3. The new interface might help Nokia in its attempt to push 150 million more Symbian handsets in the near future, but its a shame that such developments come when the platform is in the process of getting abandoned.
