Mac OS X 10.2 Jaguar [OLD VERSION]

I am a recent switcher to the Macintosh platform, I, like many of the reviewers, have used Microsoft and various other OS. I have used MS OS since DOS. I must say that Jaguar is a beautiful OS, and to add to the beauty is the UNIX core that lies underneath. However it is a bit sluggish even on G4 machines, when compared to Apples previous OS9. I have an 800 MHz Titanium PowerBook with 512MB of RAM. The CPU get eaten up by intense applications, moreso than it did when using OS9 with those same applications. For everyday users this is not a concern, but for people working on grpahics and computer media, sluggish performance is unbearable. I do however love the fact that it is almost fully customizable.
PROS:
Astonishing Looks
Exceedingly stable (compared to Windows OS)
Excellent Memory Management
Infinitely cutomizable
Good selection of third party software for graphic designers
Nice Apple Apps for the so called "digital hub"
iTunes especially stands out with MP3 fanatics (light years ahead of Winamp for Windows)
Seamless integration with both Apple and Windows networks.
CONS:
Somewhat sluggish performance compared to OS9 (due mostly to the Astonishing Looks above)
Being codenamed "Jaguar"
