What will your phone look like in 2022?. This article from Alexis Madrigal of The Atlantic looks at where the developments are going. Some key points:

• Telephony functions are largely an add-on for cellphones now; they’re going to go the way of TV and radio
• The phone market experiences shifts every five years, the case being Nokia, once dominant, but squeezed from the top by Apple and from the bottom by cheap manufacturers from India and China
• The future shape of phones will be largely dictated by the input. We’ve reached the peack with our phone on glass touchscreens; in the future, it might be 3D natural input or voice.
