Good points and I'm not arguing them. Things are now extremely more convenient then they were. What's missing is differences in approach to solving, well, everything. Everything was different from system to system (esp. mid 80's to mid 90's). People were still figuring out what to settle on. From a perspective of someone who likes to tinker with stuff, it was a blast. From a business and maybe usability perspective - it was a nightmare.

Now, when most stuff is settled-upon, it's like cars. There are differences, but not really. Turn lights to your left, wipers to your right, wheel turns left and right, there's a manual stick or automatic, pedals... it's all there, where you expect them to be. And that's good! Times were a bit more pioneering back then, naturally.
