Generation of Computers?

In such a |short| time...

You know the giant room at nasa used for the first rocket to the moon? That was full of state of the art computers of that time. A $500 laptop has more power than that whole room.

We have come a loooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong way.

Well at first they used to be big chunky things that were slow and had bad graphics but now we have tiny fast effective computer with great graphics.

Dd you know the first computer were as big as a room but were not very powerful
