Either Nokia is good at product placement or they're getting a lot of interest because LeVar Burton, also known as Lieutenant Commander Geordi La Forge on Star Trek: The Next Generation, is now using one.
In a simple two part tweet, the Reading Rainbow celeb stated "I luva my Lumia" and it was causing a bit of a stir amongst his readers (some for, some against).
Burton evidently picked up a glossy-white AT&T edition 900, the same one we're using ourselves and so far he seems to be happy with it. It will be interesting to see how he progresses with the flagship device over the next few days, after all the man was the chief engineer of the USS Enterprise (NCC-1701-E), so figuring out Windows Phone should be a breeze.
Regardless, welcome to the club, LeVar!
