I understand why Apple did it, but I'd like to be able to boot into 9 with my G5. I have customers who have files that were created on pre-OS X machines and to get any work done on those files, OS 9 is much faster. Classic is just too slow. So when I bought my G5, I kept my old G4 because it still dual boots. And, like Cipher said, there are still games that haven't been optimized for X, like UT (I actually like the TacOps mod for UT).
