It hasn't hit the shelves yet, but I was invited to write an article on the NXT for ROBOT magazine issue #4. I cover the retail version and a bot I built that used all the sensors, motors, and as many parts as I could throw at it... ran out of the small black connectors, Hassenpins, all the white beams, and a few other parts.
The editor, Tom Atwood, also managed to get a good interview with Microsoft regarding its new Robotics Studio that is featured in the issue.
