Got a pretty cool infographic here that takes a look at some of the most important computers in history. I was a C64 kid myself, what did you all have? Image from: http://www.fish4parts.co.uk/blog/10-defining-devices-computing-history/
Leaving out the IBM PC 286/386/486 in the 1980's is a bit weird. They made the business market (Apple was for academia for the most part back then.) Also completely ignored the Unix boxes like Apollo, Sun and DEC Mini-VAX workstations that took out the minicomputers, which, in their own right, helped to take out the mainframes of the 1950's - 1970's. What about the Cray or Amdahl supercomputers in the 1980's/1990's? Finally, until Windows 95 was released (in 1996) businesses were not fully committed to outfitting most of their employees with computers. That really changed the landscape in the business world which has always driven the computing market.
