Nokia’s Symbian UI isn’t the hottest UI on the block at the moment, but you can be sure that Nokia is working hard to sort that out. As you know, Symbian^4 devices should be expected to ship in early 2011, and conceptual interface designs have started to pop up, so if you’re the kind who likes to voice your displeasure, this would probably be your chance (not when it’s finalized and released). The new UI will be built upon Qt and Orbit, which should help Nokia lure developers by making apps easier to build and update.
