We went from arcade games to Pong, to Nintendo 64, to Kinect and now games you can download and play instantly on your phone while on the go.
On the go phones, used to mean a phone booth then people with money had car phones with a mobile operator and from there we had mobile phones the size of a brick. Phones gradually got smaller, then they got smarter and look where they are now.
Computers? They used to take up an entire room and you needed thousands of punch cards and a degree in order to run one. Then home computers hit the market, we DOSed until Microsoft opened a Window and now you can carry a computer in your pants pocket, no wires, no punchcards.
