> A lot of what used to be consumer electronics exists on everyone's smartphones. No more clock radios, walkmans, boomboxes, tape decks, VCRs, DVD/CD players, landline phones, etc. I would bet Bluetooth speakers have essentially replaced home stereos for many.

I still seem to use a lot of electronics: bluetooth and wired speakers, headphones and earphones, power strips and adapters, USB cables and gadgets, SSD enclosures, phone accessories, game systems, all sorts of computers, tablet/e-reader, monitors for computing/gaming/video, musical instruments and amplifiers, functional and decorative lighting, chargers for everything, networking/WiFi stuff, automatic cookers, etc. RadioShack and Fry's used to sell those things.

It's a shame that the maker/DIY electronics revival turned out to have limited appeal, because I'd like to visit a store that had Raspberry Pi and other microcontroller boards, components for real-world interfaces and robotics, 3D printers and supplies, etc.

In addition to the electronics components aisles at Fry's, I miss their PC component section. And their convenient return policy. I'm surprised that there aren't more shops for PC customization. I also wish there were a shop where you could put together your own custom mechanical keyboard, picking out switches, keycaps, etc.

Mechanicalkeyboards.com actually has a storefront in Arizona. They host meetups for the local enthusiast community, and you can buy the various components over the counter.
