It's not official until Microsoft says it is, but the image above of the rumored Microsoft Arc Touch Mouse was just snagged off a German online store. Amazingly, the mouse arches its back for comfortable mousing before packing flat for easy transport. The mouse features touch-scrolling, a battery indicator, the ability to track on most any surface, and a 2.4GHz nano transceiver that no doubt plugs into your laptop's USB port. Yours soon for €69.99 ($69.95 rumored)... right, €0.99 more than Apple's Magic Mouse or Magic Trackpad sells for in Germany. Ships in 5 to 10 business days according to notebooksbilliger so expect this to get official real quick.
