@p @lanodan my Newton MP2100 and Psion Organiser II XP still work perfectly, as does the "Fat Mac", SE/30, Duo 230, and Mac "luggable" portable. Even the NeXTs still run just fine. About the only crufty bits are the HDDs, and the monorchrome NeXT monitor -- the color one is just fine.

Once upon a time, expensive things were expected to last. Now you can get a $200 laptop, but it'll likely be dead in < 5 years.
