MoGo manufacturers three Bluetooth mice unlike anything you’ve seen before: the mouse folds flat and stays tucked away when unused in your laptop’s ExpressCard/54 or PC-card expansion slot. The slot not only provides convenient storage, it also charges the battery.

MoGo’s original Mouse BT debuted a little more than a year ago. It features two buttons and a scroll pad (not wheel) and is compatible with both Windows and Mac OS X, although only Apple’s older PowerBooks have the necessary PC-card expansion slot to support it.

More recently, the company released the Media Mouse X54, which adds media player controls allowing the mouse to serve double-duty as a remote, and the Presenter Mouse X54, which features extra controls specifically tailored for presentations and a built-in laser pointer. While MoGo says both mice support Windows and Mac OS X, no Mac has an ExpressCard/54 slot (the MacBook Pro uses the narrower ExpressCard/34), meaning you’ll have to use MoGo’s X54 Charging Cable ($19.99 currently out of stock).

Looking to buy? NewEgg carries the MoGo Mouse BT for $39.99 after $20 rebate, the lowest price around.
