Getting smaller and smaller

I was watching the last episode of the current season of Mad Men the other day. It featured the a story around the first moon landing.

One of my kids said that there was more computing power in an iPhone than the room full of computers that it took to land a man on the moon.

It's a stat I've heard many times before but this IBM ad from around 1980 shows it is quite probably true.

The storage capacity of the computers in the back row of the ad is 60GB.

That's twice the size of the USB drive that I keep in my workbag!
