So I was one of the lucky ones got the early invite (and happened to be home from work sick today).
Command Center is awesome if you're willing to put your DAW online. It functions as a download/installation manager. When you log in, it tells you what products you have (Connected Products only) and if they are installed/up-to-date. The best part was it was basically click and walk away download and installation.
As far as the software itself, I haven't had the opportunity to try any of the new features yet, but the control bar looks really cool. No glitches importing settings from my X3 producer and no glitches opening up an X3 project.
More to come as I delve deeper into the software tonight and later this weekend.
