Nokia's soon-to-be-flagship will be the Lumia 920, which boasts advanced navigation capabilities and wireless charging, where users can put the phone down on a base station or pillow to juice up. But perhaps the most innovative feature is PureView Imaging technology, which developers say makes the camera as good if not better than camera-only cameras.

"Inside this smartphone is floating lens technology that surpasses the optical digital stabilization systems of most digital SLRs," Jo Harlow with Nokia said. "The technology reacts to the minute movements in your hand to balance the lens so the shutter can stay open longer. And more light means brighter, clearer images without flash, even indoors and at night."

And certainly, apps are a big reason people choose one phone over another. So Microsoft is appealing to app developers by telling them they can create an app for any Windows 8 device (PC, tablet or phone) and that app will work on all the devices.

"We've done a lot of work to standardize the foundation, to give developers across the family of devices an opportunity to build applications that they can monetize in amazing ways," Steve Ballmer, the CEO of Microsoft, said.

As for when Windows 8 phones will be available on which carriers and how much they'll cost, all developers are saying is they'll be out by the end of the year.
