That tradition continued Monday with the unit designed for mobile users, as well as updating its Touch Mouse to better support Windows 8, expected to be released at the end of .

The "Wedge" mouse ($69.95) and keyboard ($79.95) connect to a notebook or tablet through Bluetooth 4.0 so you don't have to worry about cables or USB transceiver.

The Wedge Touch Mouse can fit in your pocket and supports four-way touch scrolling and navigation, which minimizes the rodent's real estate requirements. BlueTrack Technology is also supported by the device so you can obtain top performance from the mouse regardless of the surface it's operating on. Another nice feature is its Backpack Mode. That conserves the unit's battery life by powering it down when the computer it's paired to powers down or enters sleep mode.

The Wedge Mobile Keyboard has a very slim profile and has a Windows orientation, supporting the operating system's hot keys and media controls. To protect the keyboard from the elements, it includes a durable cover which, in a clever turn by Microsoft, can, when not in use, double as a stand for a tablet.

If you can live without extreme slimness, you can save a few bucks with Microsoft's two other new offerings: the Sculpt Touch Mouse and Sculpt Touch Keyboard, both Bluetooth devices selling $49.95 each.
