I don't want to rain on anyone's parade but i was in my uber-cool mode when i saw what could be done with gpu acceleration and filters as cs4 was preparing to launch (don't get me started on flash cs4 which is a pain in the rear) .. but the end product proved to be disappointing, it didn't live up to the expectations. I might be reserved on this one, but i doubt that the finished product, cs5, will be anything close to this. Final argument .. it's Adobe we're talking about.
Let's face it
