Got this idea from my brother who owns a PowerMac G4 1Ghz Dual (not his current computer). With his computer, he had virtually every problem that Apple admitted the computer had. Drove him nuts, especially since his job involves a lot of computer work (audio/music design for media). Apparently in the not-so-distant future, he will destroy this machine, as it has caused him so much stress. Personally for me, my worst would be my old Clamshell 366mhz G3. Simply because it would be prone to frequent kernel panics and also problems with OS9. So everyone else, admit it... somewhere along your mac-line you must have had a really sore thumb. What is your worst mac ever owned?
