It's true, removing the battery is mildly annoying. But I can probably count on one hand the number of times I have added or removed a microSD card from my phone. It's just not something I do regularly--Get a new phone, plug it in, and forget. Maybe remove it every few months to back it up to my computer.

I pop mine in and out all the time, it's been the quickest way to move large files on/off the phone ever since Android lost USB mass storage support. MTP & PTP are horrible.

You're missing the use-case for folks that use it for large data transfers for video files. Having to shut down the phone to do that is burdensome. It's why the new iPhones with USB-C that can record directly to flash drives are being praised.
