floppy and no slots
We had one of these in our multimedia lab at IBM when it first came out (we were testing the web view of our product at the time). Right off we found it was nearly unusable in our environment. Our lab was token-ring only, it was weeks before we got a phone jack we could use with the modem, and the lack of a floppy meant we couldn't even test our generated HTML & MVR files off of a floppy disk. A year or so later we eventually got an ethernet connection, but for a while it was a fancy but not entirely useful toy.
And eventually we got a replacement for that abominable "Babybel Cheese Mouse" the machine came with.
Years later I got a rev.D version of the iMac for real cheap at a tag sale (lost it in a house fire though).
