It's not just Microsoft who seem to be out of the game so to speak. What's going on with Nokia? It's taking them forever to come up with a device and/or platform that seems like a credible competitor to Android and iPhone OS.
Nokia switched tracks, abandoning Symbian for the smartphones and putting their chips on Meego embedded Linux and Qt for the UI.
There's a huge effort to make Qt into a higher level framework that can be used like Cocoa Touch or the Android UI elements. The Qt Declarative/Quick stuff is being advanced as quickly as they can work, but after working with the latest stuff they have a ways to go.
I have a hunch Nokia thinks they'll be able to quickly catch up.
And that makes me somewhat sad. I've been a user of Nokia for 10 years and I allways loved those devices. When I purchased my last phone, 1.5 years ago, I gave them a vote of confidence and got an E71 instead of an iPhone.
