We needed more memory for my daughters Kindle Fire (common problem) and we were just shocked when 64GB showed up and was about the size of a dime. I mean, really? It seems like just a few years ago, I ordered a 512MB memory card for a camera and it was 3 times this size. It's a big thought when you start thinking about all the data within ones device, house, city, state, etc. Especially when so much can be stored on something so small. Technology is amazing and scary.
