Mac OS X Apple has just released a new web page with developer information concerning Mac OS 10.5, Leopard. Among other things, the list includes: OpenGL 2.1, resolution independence, the adoption of the Mandatory Access Control framework from TrustedBSD, Code signing, and much more. And yes, boys and girls, there are screenshots as well. Update: Apple also launched faster MacBook Pros today. Update II: Screenshots of Leopard from ThinkSecret.

I don't think you have much to worry about with your PowerBook as long as it has a "fairly" recent graphics card. Here is a list of G4 Macs inside and outside of the office that I have run the Developer builds on:

1) 12" PowerBook G4/867 MHz 1 GB RAM - Runs quite well albeit no Core Image acceleration. But Spaces and Expose works very fluidly. Overall, I see a subjective speed increase on this system over Tiger.

2) 400 MHz G4 Sawtooth 896MB RAM with upgraded NV 5200 (from the closet of deprecated parts) - Amazingly this system is running Leopard with no problems whatsoever. Not the fastest system ever but it does work without hardly any hiccups.

3) 700 MHz G4 iMac with 1 GB RAM - This system works very well with Leopard, even though the 32 MB video card inside doesn't support Core Image Spaces and Expose work fluidly. Time Machine is not as fluid as it could be (Core Animations requirements are the same as Core Image)

4) 15" 1.5 GHz PowerBook 1.5 GB RAM - This system works VERY well with Leopard. Core Image and Core Animation is both fully supported on this (my) laptop. Also, as in most of the other systems that I have tried my copy of the Developers build (newest) on I have seen a subjective speed increase.

I don't think you will need to worry about not being able to run Leopard on you system. Though some of the fancy effects will not be fully enabled if your system does not fully support Core Image.
