At 7mm thin and built with anodized aircraft grade aluminum, the Belkin FastFit Bluetooth Wireless Keyboard Case ($79.99) is supposedly the lightest wireless keyboard for the Apple iPad mini to date.
It has secure-hold magnets that snap the keyboard easily onto the iPad mini and with Belkin’s TruType keyboard you are assured well-spaced keys that allow for fast and accurate typing. The case features low-powered Bluetooth 3.0 connection and 200mAh that can last for 155 hours of active use.
