Then why bother with old Macs at all? You're trying to apply logic to a hobby, which simply doesn't work. I have a 512K *entirely* because of ChipWits, a game that was given to me for my birthday back in the mid 80s. Never mind that I can play it via an emulator on my G4.
None of this needs to make sense. We do this because we enjoy it - there doesn't have to be a practical application for anything we do.
