I've tried to look this up but I can't find anything. As far as I can tell, the controller bricks (the white ones w/ buttons and a screen) are exactly the same and the only difference is NXT 2.0 comes with different sensors, parts, and software.
Is this correct?
If so, are NXT 2.0-generation sensors compatible with NXT 1.0? Can the NXT 1.0 be upgraded to run NXT 2.0-compiled software?
