The “era” is going on just fine,but without Radio Shack in the form of SparkFun, Adafruit, Make Magazine, Itead Stdudio, and many others. Someone like Hobby Lobby could use the Radio Shack chain to extend a broader hobby and DIY presence to rural areas. Internet shopping and waiting for delivery are no fun in the middle of a project, else Hobby Lobby and Joannes, etc would be sucking wind too.
Given advances in 3D printing; RadioShack could once again be a electronics components store — walk in say what you want, have them manufacture on-site... bang!
(Though it might take a while to break even w/ electronic components only; perhaps they could also be the Kinkos of 3D printing.
