I remember Pong; we had that when I was a pre-teen/teenager... but I think it was shortly after that, that I discovered boys, so I didn't give computers too much thought after that.
I didn't get on the PC bandwagon too quick, my 80s were mostly occupied with bars, white powder, rehab, divorce, remarriage, pregnancy, and motherhood... but with a baby at home, I had to do something QUICK to spare myself soap operas - so I got that Tandy 1000 in '89, got a copy of "DOS Power Tools," and basically used it as my "holy scripture" for the next few years, learning batchfile stuff -- before Windows, you recall, we didn't have that handy timepiece down in the lower right, so I fixed my command prompt to show the date and time -- my friends were mystified about how I did that, apparently never having heard of "environment variables" -- they were mostly all so intimidated by MS-DOS, they barely had the nerve to turn a PC *on*, nevermind make it do anything useful.
There are still tasks I drop to the command prompt to do, it being so much easier with wildcards to rename a whole directory full of files, than to do it one a time in Windows. 
It's on the last page, so I can't see now who said they worked at Radio Shack... I worked at Radio Shack Computer Center, at Summit Place mall in Pontiac, MI, during 1989... but I was so much more occupied with playing with the computers, my sales career never took off.
Which was fine with me, at the time; I much preferred being at home anyway, with baby and electronic baby. 
I didn't discover the internet too quickly, either; just about the time I got on the internet, was about the same time I started to always go outside to smoke; when I first got the internet, I had a 14.4 modem, with cable downlink, but dial-up uplink, so I could click to open a site, go out and smoke half a cigarette before the site was fully loaded!
Really I much prefer my Xfinity 25 megabit connection!!!!!
