We'd argue that the "wow" factor still isn't there quite yet, but we'll admit: Symbian^4 is clearly going to be a bit of a departure from the versions that came before it. The Symbian Foundation has posted the first handful of home screen UI shots on its developer wiki recently showing redesigned widgets, app categories and search, pop-up menus, and a standard-issue numeric touchscreen keypad -- and unlike Nokia's concept videos from before, these are from a real emulator running real code. While MeeGo is still expected to dominate the high end of its range, Nokia's expecting to use Symbian^4 in at least some of its devices by early 2011 -- and knowing how these guys like to go big with global roll-outs spanning tens or hundreds of millions of devices, this is a UI you might end up getting to know extremely well within a year or two.
