I took the plunge and updated my Apex from 4.1 to 4.2. You guys had me worried that this was going to be a lot of headaches, but it was the smoothest yet. For the first time, I updated the controller with my macbook (as opposed to a window's box). Maybe it was easier cause its a mac?
I'll play around a little bit more with it to see if I notice much difference (other than the dashboard). Might have to add a web cam now that the dashboard will link into one.
