The Nokia Lumia 800 and Nokia N9 are two beautiful smartphones, but the way that their MicroSIM Tray and USB ports are designed is not very convenient. It’s hard to open, and the flap often breaks because it’s not very strong. I personally don’t like it because opening the door every night to charge the device gets annoying, not to mention accessing the MicroSIM tray for the first time was really difficult. The Lumia 900 replaces this mechanism for a simpler USB port available without opening doors, and an iPhone style clip-to-open MicroSIM tray. This is a much better approach, many reviews I read complained about the Lumia 800’s USB door.
Thanks Engadget for the Lumia 900 pic!
