I got the original iMac G2 233 MHz for my kids back in the day, but it's long gone. My mother in law, however, is still using my old iMac G4/800 (Flat Panel) "Luxo" model. Running strong with Jaguar (OS X 10.2) and a whopping 512 MB RAM. So what's everybody else running? My day to day machine is an iMac Late 2010 27" with the 2.93 GHz processor and 12 GB RAM. But the old PPC-based Luxo iMac is still seeing service!
