Not saying it wasn't useful for you, but I've literally never once used my SD Card reader. Having the option for putting it in would be nice for customers like you, but I'm happy it's not there for my laptop.

I get how you could not see it as useful, but I'm baffled by going all the way to being literally HAPPY it's not there.

If it's there, and you don't use it, it doesn't cost you anything.

Yeah it totally depends on your workflow. If you do a lot of photography (I do Drone photography) you need an SD-Card reader to get the raw images off of your drone. I have a dongle so it's no big deal, but I would love to have a micro-sd card slot in my MBP. It's the only dongle I use regularly.
