I use CS as well, never used 7 or below, but I am still trying to figure out some of CS's features...
Other than being a resource hog, having a couple other filter that you can download to use on ps7, and being more organized. Yea it's the same. But being a resource hog is a big downfall. Remember kiddies, newer isn't always better.
adobe hasnt even made 10 so I seriously doubt that he has it I'm using CS works like a charm, but not image ready CS I have to edit the date on my PC to use it(anyone now how o fix that? Send me a PM, any help appriciated)
