While I share your sentiment, in actuality they were likely already a laughing stock in 1985 when this Jobs interview ran, "Radio Shack is totally out of the picture. They have missed the boat. Radio Shack tried to squeeze the computer into their model of retailing, which in my opinion often meant selling second-rate products or low-end products in a surplus-store environment."

I find there's a lot of romantic nostalgia. I accept that there are doubtless examples where Radio Shack stores were hubs for ham radio or electronics activity or whatever. And, certainly, the average skills of Radio Shack employees are a lot lower than they were at one time. But Radio Shack always sold huge quantities of crap (e.g. laughable stereo gear) to people who mostly didn't know any better along with generally overpriced cables etc. at a time when random components weren't necessarily all that easy to find elsewhere.
I remember Radio Shack being useful when I needed an adapter or a cable. But I can't say that I ever particularly loved the place.
