I'll never forget the very first day I saw this little tiny typewriter sized keyboard with an ugly green screen monitor in the early 80's. I was with Sperry Univac (a large mainframe manufacture in competition with IBM) as a salesman selling mainframe computers, after having been a field engineer then systems analyst before that.
I was visiting the Travelodge motel chain's headquarters in El Cajon California where I was visiting to see the data processing manager. I walked into the computer room and he was sitting looking at his new Apple computer's display which had information laid out in a grid. He commented "Jerry this little guy can do stuff your big mainframe computer can't do". I scoffed at first but hearing that greatly concerned me... as in how could that be? His Apple was running the very first commercially available spreadsheet called VisiCalc, it was like the dinosaur predecessor to Excel. He said watch this... he changed the numbers in one cell and that caused a ripple effect through the rest of the display. He said he was performing a bunch of "what if" scenarios, cost-wise, for the motel chain. He was right, my million dollar mainframe was incapable of doing anything like that in an interactive manner.
That was when microcomputer usage started exploding in the computer world, it changed the world. We still have big roomfuls of computer systems but wow, Apple really changed the world with that first Apple.
Personally I can't figure out how to use an Apple or Macintosh product, my mind is just more of a Windows/Android type I guess lol.
