Microsoft has announced a hardware update to their folding Arc Mouse. The new Arc Touch Mouse keeps the same basic arc shape, but adds two cool new features. One is a capacitive touch scroll strip that allows you to swiftly navigate with the flick of a finger. The other feature is the ability to flatten the mouse for ease of packing. Nifty huh? This is a 2.4GHz wireless mouse with a snap in USB nano transceiver and up to a 6 month battery life. The Arc Touch won’t be available until January 2011, but it is currently available for pre-order through Microsoft for $69.95
