Solid review Lee - I know now much more about digital noise than I did before.
I'm frankly kind of amazed at the speed issues - a Core i7 920 @ 3 Ghz should be able to tear through
anything other than video encoding really, really fast. I think you're kinder to this program than I would have been - if I was editing photos and I had to wait more than 5 seconds for any process to finish, I'd skip it. I'm really hoping Topaz Labs understands how important speed of workflow is...
