Remember the ps/1?

One of my fondest memories from childhood was when my family got our first gateway computer. We had one computer before this, an IBM ps/1, on which I mostly played a game called "Alleycat"; but for us getting a gateway was a big deal, because there's such a big difference between it and the ps/1. My interests didn't change much at the time; my new game was "Star Wars: Rebel Assult"; but the whole experience of the computer was different. There were so many programs on the gateway that the ps/1 couldn't run. The gateway, for example,  had microsoft word; the word processor that the ps/1 used was a blue screen with grey lettering.

Today the gateway is not only obsolete, but it is so behind in terms of technology that it triggers feelings of nostalgia just remembering it. Just remembering the strange sound of the modem dialing up...weird. This just shows, however, how much technology can change. From the ps/1 to the gateway, and from the gateway to any given computer currently used by anyone, there are major advancements in technology. What makes this interesting is that the ps/1 is a computer from 1990, which makes these advancements span only 20 years. That's insane.

Obviously, in order to do anything in today's world, one must be proficient in more that just computers to be proficient with technology. I'm not sure what much of this newer technology is which is used in classrooms, but this is exactly what I hope to learn.
