I think this idea of a typewriter would be a fantastic jumping off point for a project. Not understanding how the device works is what can instill that initial panic in older people that leads them to not want to use a new phone. The iPhone is successful in that aspect because it is so friendly but I think, in this scenario, there’s more then one way to skin the cat. Taking the idea of a visible, physical, quantifiable action and reaction as a jumping off point would yield some cool designs.
