Aah. The smart phone: Linchpin of modern society. They come with much larger touch screens these days, and these new models can be a tight fit in your jeans.
Furthermore, you spend all day wiping the finger marks off the screen, only to replace them moments later.
So: Here is my new invention.
Here's a pair of jeans with an extra external pocket sized to fit your Nexus 5*. So far so good.
However, the pocket is made of screen cleaning cloth, so you also have a place to wipe the screen that is made of exactly the right material.
My idea. My patent...
*Other smartphones are available, some of them made by Apple apparently.
