We've just stumbled across the new Lumia 800 here at Nokia World, and yep, we can confirm: it feels a whole lot like an N9 running Windows Phone 7.5. For many, that'll be a good thing considering how stellar the N9 hardware is. Nokia Drive, Nokia Music with Mix radio, and a Nokia-exclusive ESPN app will all come preloaded on the Lumia 800, but otherwise you're looking at a bone stock Windows Phone Mango experience. That includes the typically swift responsiveness of the platform, with a Qualcomm Snapdragon S2 (1.4GHz MSM8255) doing the gruntwork -- typical for Windows Phone, but a change from the N9's OMAP3630. Other tweaks from the N9 include the addition of a physical camera key -- styled and functioning exactly as the volume rocker and power button next to it -- and the repositioning of the dual-LED flash from the side of the 8-megapixel camera to a spot directly above it (when the phone's held upright).

Sadly, as hinted above, none of the N9's UI innovations have made the jump to the Lumia 800. There's no double-tap-to-wake functionality, no swiping out of applications, and the software keyboard is stock Windows Phone -- improved in Mango, but still not as sublime as the haptic-enhanced version you'd get on the N9. Still, the superb build quality and Clear Black AMOLED display you're familiar with from the Harmattan device are both present and accounted for here. The feel in the hand is close to the best around and the blacks are deep enough to create the illusion that onscreen items are simply floating atop the curved Gorilla Glass screen. Another small difference from the N9 is that the 800's viewable display is only 3.7 inches (800 x 480 resolution) in size, down from the N9's 3.9 inches (854 x 480) because of the need to accommodate the capacitive Windows keys. Also strangely absent is the front-facing camera, which was found on the bottom right corner of the N9, but is replaced by the status LED in Nokia's new Windows Phone.
