As many of you know, I'm a senior (80 Yr old), and PPC has been my hobby ever since Apple and Stevie dumped it in favor of Intel. Long story - short, I've had and still use many PPC systems, but in the end I keep coming back to my G5 quad. As older PPC sytems go, my G5 is smooth, quiet and fast enough to be very usable, even in todays Internet oriented culture. I still maintain my PowerBooks and Cubes along with several G4 MDD's, but all in all the quad is my go-to machine when it comes to PowerPC. Plus the bonus, living up here in Canada I can use the extra heat.
