I have fond memories of my mother smacking my hands whenever I played around with her typewriter. The keys are hard, definitely not ergonomic and made this amazing clackety sound. I loved it.
And then my Dad got my sister a computer and I ended up being the unpaid home-based secretary for his mosque and political activities. :p
The toy in this video definitely brings back fond memories and ought to be suggested to the luddites who had to be dragged kicking and screaming into the 21st century.
