I really don't the whole Ranting about not using PPC OSX online. Between the low amount of exploits that run on PPC and as long as the machine is behind a firewall hardware preferably but software is fine or both if your really concerned the risk being compromised is pretty close to nill. Heck I still run Win2K & Win98SE behind my network firewall for internet use and its never been owned. I'm not suggesting sticking ether of them on a direct connection to the net just saying if you have a proper network installation preventing access from the outside and don't do dumb stuff like install random binaries offered up via popup you are as safe as your going to get. Like my Network design professor said "if you want a completely secure system unplug it and smash the HDD with a hammer." if someone wants in bad enough they will find a way all you can do is make hard enough that they look for easier targets.
