I must say, I miss having Radio Shack around. When I was growing up, I read the catalogs until they fell apart. My first stereo system was based around Optimus components, and some of the first computers I myself owned were from the TRS-80 series. In more recent years, I would stop by a Radio Shack store whenever I happened to be in the area, even if there wasn't anything specific I needed. Sometimes I did buy stuff, usually an audio cable/adapter or parts for one of my many projects (when they had something I could use, anyway). For awhile, they were a great place for obsolete formats, like 5.25" floppy disks, reel-to-reel tapes, and Betamax tapes. This changed over the years, as they switched more and more to cell phones, and the 'good' stuff went away.
Of course, I'm lucky to still have a few old-style electronics stores in my area. Two of them are 20-30 miles away, but one of them happens to be in the next town over from me. They used to be a Radio Shack franchisee back in the '70s and '80s, but went independent in the '90s. Most of the store is floor-to-ceiling racks of NTE and Philmore components (resistors, capacitors, transistors, ICs, etc.) plus cables, CB supplies, telephone stuff, etc. Not as wide a variety as Mouser or Digikey, but they have a pretty good selection. Also, they still have some of the old Radio Shack inventory left over, which the owner digs out from time to time.
