Congratulations, this is a pretty great specimen!
This is a pretty great specimen of what was unfortunately a terrible model. It's the fastest PowerBook G4 to boot directly into Mac OS 9 without requiring the use of Classic Mode, but I never found mine to be faster at running anything than my 500MHz PowerBook G3 ("Pismo") was, and to be honest, I wasn't impressed with the way the screen died on mine just 92 or so days out of the warranty period. It turned out that a fresh cable fixed it, but what a bad death for such an expensive piece of "professional computer."
I still remember the serial number to my TiBook/1.0, after calling AppleCare about it so many times while it was still under coverage. After "the incident" I ended up just putting it on top of a 17-inch CRT monitor and using it like it was a desktop for about six months before trading it away for the pismo that replaced it, and was a better computer from a physical standpoint in almost every way. In theory the Pismo was slower, in the real world it was nearly the same speed, and most OS 9 apps I ever used (until you got to tasks like rendering really large video projects or 3d scenes) were already running at absolute top speed on the Pismo anyway.
