Since I have a pair of 20" Apple Cinema LCD displays, and Apple keyboards, all of which have USB hubs & ports built into them, I never ran into any shortage of USB ports while running MorphOS on my G4 & G5, but Apple monitors and keyboards aren't the solution for everyone I guess. My 20" Apple Cinema display monitors are pretty nice though, so if you can get one at a good price in the area where you live, that might be an option you would find acceptable, but it only gives you one extra USB port.
