I've been an MC user for about two years, and its just extraordinary how fast this software develops and updates: two years when I downloaded the trial software, there was no Gizmo, no Red October, limited TV support and video conversion, basic theater view, no WASAPI event style, no convolution engine, no Carnac... countless other features added, of course; that's just a casual short list of major features off the top of my head.
Interact is a great place as well. A lots of generous and bright minds come together here, making Interact a great source for information about home and mobile media technology. It's also one of the few sane neighborhoods on the internet.
Thanks, cheers, and look forward to seeing what comes next! (i.e., hope the beta boards are buzzing...)
