Portable notebooks or tablets may let you access the internet on the go, but working on their smaller, cramped keyboards is not as easy as on a standard keyboard. Providing a solution, Japanese gadget manufacturer Thanko has come up with a full-scale USB keyboard that separates into four connected quarter segments to fit your pocket for easy storage. Measuring 350 x 129 x 10mm (when open) to offer regular 19mm key pitch, it folds into a pocket-size 91 x 129 x 20mm rectangular accessory to slip in your pocket with ease. Compatible with standard Windows and Mac operating systems, the foldable keyboard weighs just over 8 ounces, allowing easy transportation.
