You know how when you grew up, your parents and grand-parents always said stuff like "I remember when I was a kid, we didn't even have X", where X was airplanes, or TV's or ice or whatever. I actually found myself having one of those moments in the OfficeMax store today. I remember when I got my first hard drive for my IBM PC in the very early 80's. It was 10MB, cost about $500, and my one thought at the time was "I'll never be able to fill up this thing".
Today at the office supply store at the register I made an impulse purchase for a new USB memory key. My son stole mine to use to take stuff back and forth to school, and I wanted a larger capacity drive anyway. So here I was buying a 1GB key, with 100x the storage of that first hard drive in a package about 1/100 of the size of that hard drive, and I was buying it at the cash register from a rack next to the gum. Pretty cool.
