I've had the opportunity to beta test the newest version of Photoshop these past few months, and while I can't share what new and trick tools are in this edition, I can tell you that it is very user friendly and offers a lot for the laser user.
The attached photo was cleaned up and prepared for the laser in less than 3 minutes. . .all within CS5. . .and it had a seriously cluttered background. The test was run on gold alumamark.
