Brett, My G4 (PCI Graphics) has been in almost constant use since I bought it in 2000. I have added memory and a USB2 card and a Pioneer 111D DVD burner. I also own two Pentium 4 level PCs. However the G4-400mhz is my computer of choice. Because it has always done what it was supposed to. My PCs, while of ostensibly good quality, are "problematic" and unreliable. I blame Windows XP SR2 for that. Windows is simply cheesy. I will probably install Linux Ubuntu on one of the PCs in the near future. However the G4 has been great and I imagine that I can use it for the next few years. I actually intend to use it until 2010 in one capacity or another. Nevertheless it is now slow if I want to use some of the newer Apple software. So I am looking into a new Mac Pro with the hope that it will be just as reliable. Bill
