The Radio Shack I knew and loved, growing up, was one of the early computer stores, among other things. The TRS-80 line of 8-bit computers, despite being much maligned by proponents of competing brands ("Trash 80" as they liked to call them), were solid, reliable and capable computers in their day. I *still* know several people who have their old TRS-80 Model 3 or 4 computers in good, working condition to this day. (If you purchased that optional dust cover Radio Shack used to sell for them, and used it religiously, the machine might even LOOK almost like new!)
The parent poster is also correct that Radio Shack home stereo equipment was pretty good stuff, all in all. Like every brand, they sold a few "duds" too, but products like the old Minimus 7 die-cast metal bookshelf speakers were even critically acclaimed in magazines like Stereo Review. (They eventually got renamed Optimus 7, with the 77 being a larger wattage version with about an inch larger woofer.) I believe some of their component stereo receivers were made for them by Pioneer, but designed custom for Radio Shack so not just identical to Pioneer models for sale elsewhere.
Radio Shack used to also be one of only a few really good "go to" places for things like police scanners, weather radios or shortwave radios. Sure, other brands were arguably "better" but were typically only available by mail order or at specialty shops. At least with Radio Shack, you could recommend a particular one and know anyone could run down the street and grab it at their nearest store. The availability of some of these also meant readily available hardware modifications. (I remember downloading instructions on how to cut one capacitor off of a board in one of my Radio Shack scanners to unlock the ability to scan a whole portion of the frequency spectrum that was otherwise locked out. Pretty cool enhancement for nothing but the cost of my time to open it up and cut one thing.)
When they tried to change into a mini Best Buy type of store, they really went downhill fast, IMO. I guess that was an attempt to appeal to the masses, who were less interested in electronics projects and hacking, and more interested in buying off the shelf accessories and gadgets. But too many retailers already did that better than Radio Shack ever could with their smaller stores.
At this point, I agree that R/S may need to cut back and close quite a few stores -- but it could do well to focus the remaining ones on electronics for true hobbyists and electricians, IMO. Drop the prices so they're really competitive, especially on items like ethernet cabling and jacks. Carry a full line of quality tools like phone linemen's handsets, punch-down tools and "fox and hound" toners/probes, but sell them below the high prices of places like Greybar! IMO, there's no room to make any money selling computers anymore. R/S just needs to step out of that area -- other than maybe stocking a few common items like USB memory sticks or SD cards. But definitely go back to carrying a full line of soldering irons, solder remover tools, maybe an R/S branded oscilloscope ....
