Alright, so I bit the bullet and installed Acid 4 before the update. I haven't really used it for a project yet, I've just been playing around checking out the new features. I feel like a little kid on Christmas, though. Man, it is a dream having these options available in Acid. And they really do keep it so simple and easy to use. The only thing that's not there that I would want is Rewire, but it's a likely possibility in a future version.
Check it out man, if you are a fan of Acid, WOW. Once they get a few bugs straightened out, it's over.
