If you imagine the cell phone section of a funky, Scandinavian design shop run by avant-garde youths, the Lumia 900 would fit right in. Its lightly sculpted unibody chassis and deliberate use of color scream "lifestyle product." Bold as an exclamation mark, the Lumia 900 has pure pop-art coursing through its electrical veins.
Operating system and Nokia apps
Thanks to a close partnership between Nokia and Microsoft, the Lumia 900 runs the most recent iteration of Windows Phone OS, version 7.5 Mango. As a result, the Lumia 900 can perform every software task that other Windows Phones do, too.
Since Windows Phone OS pretty much behaves the same on every handset, it's the extras that are important. LTE was the most crucial feature Nokia needed to sell this phone on our shores, and it'll be one of the first two Windows phones with LTE. (The HTC Titan II, which goes on sale the same day, is the other.)
