The PC is 25 years old! I can remember the first time they carried the thing into our office. Oh man, did it change the way we worked. We had a Wang text editor in a private network. One of these great boxes with screen and keyboard in one box. The documents we wrote we either send handwriten to the typing department who were also working with the Wang or we did it on the Wang.
We first used Multimate, Lotus, Symphony, Harvard Graphics, DOS, QEMM. Great times. The first PC I had looked exactly like the one on the picture. You could park your car on it and it would still run.
Now I work with a Tablet PC, a laptop plus I still have a couple of desktop/workstations. The price of all that stuff is probably less than what you paid for the first IBM PC.
