A 300MHz PowerBook would be a Wall Street model. This would come with less than 1MB of cache on the processor and a 67MHz system bus speed. The video card would probably have 4MB or less of VRAM. Your Pismo, on the other hand has a full 1MB of L2 cache, a 100MHz system bus speed, and a more powerful video card with 8MB of VRAM. OS X is going to be much slower on that 300MHz Wall Street.
