Last we heard, Microsoft's Arc Touch Mouse was due sometime next month; that hasn't stopped German retailer notebooksbilliger jumping the gun and putting up their product page. According to their details, the Arc Touch Mouse is a wireless peripheral that physically bends for comfortable mousing but flattens out for easier transportation. It has a large touch-scroll sensor - presumably the grey bar running between the buttons - for easier navigation.
Connectivity is via a 2.4GHz USB dongle, which stows in a compartment under the mouse during transportation. There's also a battery indicator and physical power control, while the actual mousing is done by Microsoft's Blue Track system which should make for some decent accuracy.
According to the retailer, the Microsoft Arc Touch Mouse will go on sale from October 13th priced at €69.99 ($90), in-line with what Apple are asking for the Magic Trackpad and Magic Mouse in Germany. US pricing is expected to be $69.95.
