I'm familiar with Kaleidoscope, but what is Tiger Lights?

I am happily running Tiger on one Lombard, and OS 9.04 on the other. I really enjoy using OS 9, and I'm on the Wacom browser right now typing this. The battery life, and bays are killer (I still use floppies, so it is nice to slide out my DVD and slide in the VST floppy drive in the bay).

I want to upgrade...but I'm not happy with the form factors of the MacBook Pro. Now, the MacBook Air is a different matter...but these Lombards are so darn good!
