I saw the following on another thread and it got me thinking. I started collecting Macs about a year ago (that means actively getting other people's old machines in addition to not throwing away all the stuff I accumulate on my own). Looking around my office, I can see about 13 desktop machines, 11 laptops, 6 PDAs, assorted monitors, scanners, printers, external drives, parts, and there are many more machines, parts, and software packed away in boxes. Oh, and I have started picking up old Mac books lately. I have about 5 machines on display (128k, Portable, PB100, Duo 210, eMate 300), although they don't all work at the moment... So the question stands, what do you do with the old machines you lug home from the flea market, or have sent to you from some eBayer?
