Because honestly, either those options are still readily available or I'm glad to see their backside. I mean, MacOS Classic? Sure, I can't stand the OS X dock, but do you remember how often it crashed, INITs, the awful multitasking? Or 8-bit/16-bit computing? Okay, there were some nice apps, but would I really want to go back to an era when memory was counted in kilobytes (or even single bytes)? And dial-up networking shouldn't even get the slightest of considerations. I've embraced the changes of the ever-improving technology world because they have been, for the most part, actually improvements. I got more computing power in my cellphone (which do everything a PDA did, and more) these days than a Cray had when I was growing up. If I really want to re-live the glory days of past computing, there are always emulators to remind me of how far we've come, and how limited those old machines really were.

Nostalgia for old tech? I don't think so.
