My favorite Mac of all time was a IIci, named "BigMac".

Though it's a losing battle to vote for such a machine due to the sheer percentage of faces that weren't around back then, I too have to put in a good word for my trusty old IIci, "WatusiEye." Stretched its life out as long as I could with a Daystar Rocket and other tricks.

It may not have been the speed demon, storage warehouse, Internet devourer or panoramic display marvel that my 3.4GHz/16GB/SSD/2TB Sandy Bridge iMac is, or the all-round useful, Swiss Army knife, sexy tool my Air is, but for pure computing gestalt user interaction pleasure nothing has ever topped it. And probably never will. Your Mac used to be your buddy in a way someone who's only used OS X, or even who picked up at System 8 or 9, could never understand. ResEdit forever!

It also probably had something to do with the size of the gap between it and any other alternatives available on the market at the time...
