I ditched my 486 for the original iMac the morning of its introduction. After frying that (still haven't lost hope of reviving it) got a Quicksilver G4. Went portable with dual PowerBooks, the final two 15" models. Those were/are my primary machines, but I've picked up a Performa 475, 20" iMac G5, black and white Macbooks, and a peripheral-less Mac Plus. Yes, that's more than 7, but only 7 are usable at the moment. A 6100 stayed here for a short while, but was given to a friend, as it was given to me.
I'd like to add that Mac OS 8.6 is still my favorite, after a few modifications. We held a small celebration for its recent 10th birthday.
