The Mobis Technology Wireless Fabric Keyboard is a very light 63-key nylon based QWERTY keyboard for the Pocket PC and Smartphone. The reviewer claims that this keyboard might be the best choice for consumers who want a very light keyboard with a large typing space. After all, the Wireless Fabric keyboard has a full size of 1 foot by 4.5 inches but it rolls up like a hand towel, making it easy to pack. The device is powered by 2 AAA alkaline batteries " which means that you’ll always have your keyboard handy since these batteries are available everywhere. The batteries last for up to 10 hours of non-stop operation, but you may need to pack an extra set if you think you’ll be using the keyboard a lot. The reviewer noted that it takes a bit of time to get used to the fabric keys, which means it’s not the ideal solution for those who want their keyboard to a have a bit more spring. But the fabric keyboard is water resistant, and combined with its portability and easy-to-replace batteries, it is a great choice for travelers who need to type inside moving vehicles.
