re: #154 The Very Reverend Battleaxe of Knowledge
The 640K memory ceiling was bad, but not as bad as paying $350 for a 40 MB Hard drive, only 32 of which was useable because of the DOS partition.
The worst pain I can remember was early 3D video card drivers. One time, for Christmas, I got a new video game. It required a certain, very specific version of the video card drivers - which also just so happened to break everything else. It was months before I was able to get my system stabilized.
