Here is my happy use case. Often while at work, I'll get an email that looks like this:
Which means that the family at home has been taking pictures, and my day is interrupted by a cute and often candid update of what my fantastic family is up to today.
The new cards will also upload videos, which means that I rarely, if ever take my card out of my camera anymore.
Overall, this is one technical gadget that makes my life easier and has extremely low friction. Exactly what a quality item should be.
