Thanks for the comments. Some projects are already coming to mind. It sounds like EV3 robots will be
able to go directly from one point to another without line following, similar to the small orange warehouse
robots on 60 Minutes the other night. (<http://www.cbsnews.com/video/watch/?id=50138922n
Most of my NXT projects now involve some sort of line following. So, EV3 - no more creating lined
floor mats, or maybe, we'll know in 7, 8, 9 months.
