I have used a lots of differer OS. First one was Solars, the IBM OS/2, then AIX, Then came "a shock therapy" - DOS. For a long time I can't believe that someone developed OS on which you can run only one program in same time.:) Then graphical GUI appeared for DOS - Windows 3.x - 9x
Blame that on IBM, to save a few dollars on cost it used a 16 bit CPU w/out memory protection. If they had used a motorola m68k (32 bit) CPU & an MMU chip we would all have been saved an enormous amount of agony. Although Bill G would have had to write DOS from scratch rather than buy it in. But then: IBM thought that it was only going to sell 50,000 of these machines so it wasn't really worth the bother to get the design right :-(
