The ZAGG Pocket is a wireless Bluetooth keyboard that folds up for travel -- or even to slide in a pocket.
When folded, it's 9 x 2 1/2 x 1/2 inches, and weighs 6.8 ounces.
And unfolded it's 85 percent the size of a desktop keyboard -- not so compact to crimp your typing -- and has full five rows of keys (including numeric).
It folds in half lengthwise (between the "A" and "Z" rows). The design includes two additional folding elements that form a protective cover when closed, and then unfold into a stand with a flip-out holder to prop up your device. Magnets keep it closed when folded, and it automatically turns it off when closed.
The ZAGG Pocket is available for around $64. It makes it much more reasonable to carry a keyboard for extensive typing on the go.
