We don’t know why we want it, but we do. The Pop-I is a backpack with a 10-inch e-ink screen. Using the app, you can send photos from your smartphone to the display on your bag. So as you’re walking down the street you can have a selfie on your back. The company behind the backpack, Pop-I (same name as the bag) are also working on a range of sports bags with a smaller 4.7-inch display for some reason.
If, like us, you want one because you’re curious, they’re available in the US for $99 (approx. £80) from spring 2017.
