From time to time there are such fantasies of designers, people come up with what the 'iPhone' could look like in the days of the first Mac computers. Or, people figure out what would happen if the design of the first Walkman cassette player was combined with a modern smartphone. See what happens.
And it turns out very well! Designer Pierre Cerveau needs to say thank you for this work, it was he who came up with the idea to transform the classic and iconic player into a smartphone. Pay attention to how great it was to transfer the color and all sorts of details of this thing to our time – the design of the buttons, the areas with perforation, two connectors on the upper end, one for headphones, the second for outputting sound to other sources (although you could do without this) .
Here are just the mute button is clearly borrowed from iPhone, but the rest is just in the subject. Concept ready for Sony Xperia Walkman? Well, why not?
The author also has Atari smartphone concepts.
By the way, we have already seen devices with wooden inserts (and more than once) both among concepts and among commercial models. You don't have to look far for examples, just look at Motorola.
