If you agree with the line of thinking that a picture can replace a thousand words, you would surely agree with the extension - that a model can replace a zillion pictures. So assuming that it would be boring to look at a chart, however well-done, to visualize the evolution of a device, give your eyes a treat by looking at this creation by UK-based designer Kyle Bean to demonstrate the evolution of the mobile phone.

The design captures the evolution of the mobile phone in Russian Babushka doll style - starting from the earliest Motorola DynaTAC 8000X to the current Apple iPhone. A lesson or two for schools to make history more interesting.
