Most of the things mentioned so far, to me, are more of a "so what" rather than true technology.
Yeah, PS was nice, but I still drove armstrong steering and a manual trans for many more years. I wound my watch every day while sitting on the can, so no time savings there. The calculator was nice but there was an electric adding machine on my desk, so no time savings there either.
Grandpa's 9" B&W TV was nice too, but he would only allow it to be turned on in the evening (to save on the electric bill), after I was in bed. So, it didn't mean much to me.
The newest technology that was monumental to me was the PC. I used to have to actually WRITE code, type punch cards and spend hours and hours on a mainframe. I often had to work late to finish my projects. When my company invested in an IBM 286 many of us were delighted. The only problem was now everybody wanted to use it and they only bought 1.
To me this was awesome technology because it truly saved time and improved the quality of the job.
When the 386 came out the boss stepped up and bought several of them. By then the value of a 286 had dropped and I was able to buy a used 286. Now we had a computer in the home.
The funny thing is that over the years (and after going into business for myself) I bought the newest and fastest one every time a new model came out. Most are long gone, except for my current model, plus that very first 286. It resides in a prominent place on my loading bench. Every once in awhile I turn it on, if for nothing else than to use its dos ballistics program.
The other funny thing is that it never crashes, locks up or burps at all. It only has 1 windows venue, and that is merely a menu to open the dos programs.
They don't build them like they used to.....
