The PS Raw plug in is great, the only drawback is you need Photoshop CS, and CS requires Windows XP or one of the later Mac versions. I can't remember which. Good excuse to upgrade though.
Mac OS X 10.2.4 or higher, according to my box. The current version of Mac OS X is 10.3.2.
Photoshop was one of my reasons for upgrading, but I did get a bit carried away. No regrets though. As for my other reasons, I'll just bite my tongue to prevent another futile argument :)
