I priced the full version of CS4 for the Mac and uh, no

Have you by any chance checked out Photoshop Elements? I bought that to go with my new Snow Leopard upgrades, and am shocked at how many of the Photoshop features it has. Certainly everything I use on a regular basis. I haven't played with it too much yet, but after installing it, I did a quick tour and found everything I normally looked for. And it's FAR cheaper than the full package.

Just something to consider if you get a chance in the future to explore a Mac purchase.
