Apple Watch the distance from an original prediction to actuality

Lets have a look at an early prediction of the watch sized computer and how it turned out after 34 years of development.

Byte Magazine cover from April 1981

Apple Watch advert from March 2015 ( 34 years later )

Detail changes:

Keyboard -> Touch screen

Removable media -> Wireless connection

Text screen - > Full graphics screen

Stainless steel strap -> Stainless steel strap ( or leather etc)

Nothing -> Sensors for heartbeat, location, time, motion

Nothing -> Communication connection to iPhone

Text based adventure - > Angry Birds.

Software from early version would have been text based, limited by the lack of sensors, communication and 10 years of smartphone software development.
