iMac G4 15" 700mhz
My new iMac G4 15" 700mhz (first model released) - running OS X 10.4.11 (and dual-booting to Mac OS 9.2.2 of course).
Based on the serial number, this iMac was manufactured in August, 2002. Not exactly a launch-day buy, but pretty close! Now I've got the first iMac G3 and the first iMac G4! :)
