This is nice. If you've been waiting a long time for Nokia to come up with something competitive in the smartphone market then the wait might be over, because the Lumia 920 is certainly as good as the best of them.
Perhaps the interesting thing is Windows Phone 8, based on the same core as the desktop version. It holds out the promise of eventual Active Directory integration and easier management for corporates. And it's a lot, lot sexier than a BlackBerry.
