Microsoft's portable Arc Mouse folds down to half its size for travel. But that semicircle shape can't be as comfortable as it looks. Then again, who needs to point and click and work when you can flip and drool? It comes in red or black for $60 and will be out later this year. [MaxPC, thanks Norm]
Featuring a revolutionary new design shaped like a crescent moon, Arc folds closed to reduce in size by almost half, giving consumers the comfort of a full-sized mouse with the portability of a notebook mouse. Arc is all about the fashion edge, with a stylish micro transceiver that you can leave right in your computer and it's available in two colors – red or black. It's the perfect gift for the trendsetter on the list. MSRP: $59.95
