Don't get me wrong here, I have the greatest respect for you and your work and your technical ability. But If you're running that HD system on anything less than a maxed out, high-end computer, I'm amazed. That is not your typical home computer. There are some basic, note that, basic computer editing systems that can actually run on a less maxed out home computer. Steinberg Wavelab for the PC comes to mind for that.

That said, your defense of Pro Tools is becoming something like cg's defense of Velodyne subwoofers. While they may make the biggest and the "best" at the upper price points, there are many, many other options available especially at the lower price points.
