The era of USB-C has come. The other day I threw all other cables into a box, and bought a set of USB-C to USB-C, Lightning, and microUSB cables. USB-C chargers around the house, USB-C PD power bank, even a nice small USB-C dock that works with the Nintendo Switch if the charger can do the right voltage. It's glorious.

It’s hard to see a child outside today without some kind of iDevice pumping high fidelity 192kbps stereo lossless audio into their shiny white headphones, but BACK IN MY DAY, the iPod hadn’t been invented yet. Pickings were slim. Walkmen were outdated, CD players were pricey and would skip if bumped around despite…
