There was nothing wonderful about 70s/80's computing in comparison to modern PCs. It was lovely at the time, because it was so new and exciting that we were willing to spend hours crafting the perfect autoexec.bat just to get the game to run, but getting nostalgic for that, in an era where it's as easy as clicking a title and playing is just goofy. If you really want to experience the joy of early computing, go get yourself an old computer and play with it. Not having brands to fight over is just another bonus of the commodification of PCs.
