It's used in micro controllers, drones, some cameras etc. the whole point of my post is that apple should make a line of laptops that caters to people like artists, photographers, engineers, etc. They used to, and it was called the MacBook Pro.

A perfect example of this: I was recently at EDC, a massive music festival in Nevada, and one of our lighting displays had its controller stop working. I had my laptop with me, though, so I installed the control software on it. The comical part was that I had to plug I first a dongle to get USB, and then ANOTHER dongle to get Ethernet (controllers like this talk over artnet).

It was just really annoying. It felt like I was using a fashion device for work.

Every SD card I’ve bought in the last few years has just been a microSD card with full size adapter.

Cameras need fast full size SD cards.

My full frame RX1Rii shoots 20+MP raw just fine onto micro SD.

All will, the underlying technology is the same and the 'micro' just refers to the plastic shell; the adapter is just a spacer with electrical contacts.

That’s not remotely true. I shoot all kinds of video and record audio onto micro SD.
