For a while, I had the pair of the first 17" iMac G4 (which has the distinction of being the last "primary line" system capable of booting into OS 9 - only the "revived" Classic-bootable 1.25 GHz Power Mac G4 and the education-market eMac could boot OS 9 and were introduced later,) and the white Core 2 Duo 17" iMac next to each other. The first and last 17" iMacs. (That you can see in my thread about them.)
