I don't mean to one-up (ok, actually, I am), but my first computer was from Radio Shack as well. A TRS-80 (later, it would be called a Model I, but at the time it was the only model so didn't need a steenkin' model badge). 4 whole kilobytes of RAM. A tiny BASIC interpreter in-ROM which probably started life as someone's punched-tape baby. 300 baud I/O for highly unreliable audio cassette storage. A video monitor that started out life as a gutted-down RCA black-and-white TV. It's the reason I'm a SW/Systems Engineer instead of an Electrical Engineer.
I was in a local Radio Shack late last year. There was virtually nothing there for me. I guess some of the Arduino toys were cool, but for my degree of urgency I'd be far better off shopping online. And their consumer electronics stopped being interesting sometime shortly after the 1980s.
A little sad, a little nostalgic, but the same way as discovering the ol' neighborhood has changed so much and all the landmarks you remember are gone. If they bulldozed the whole thing, it wouldn't be much different.
