With Windows 8 to launch soon-ish, your customers will want upgrades on the Microsoft peripheral selection, offering x4 wireless battery-powered and tablet-friendly keyboards and mice.
Most interesting are the Wedge Touch Mouse and Keyboard-- Bluetooth-enabled compact devices with Windows 8 features (such as shortcut keys) and pleasing industrial design.
The Wedge Touch Mouse features 4-way scrolling and Bluetrack technology, allowing customers to use it on any surface. Meanwhile the Wedge Keyboard has a removable cover that doubles as a multi-angle (via centre joint) tablet stand and a set of hotkeys for launching Windows 8 menu functions.
The Explorer Touch Mouse and Bluetooth Mobile Keyboard 5000 get an update, and are now the Sculpt Touch Mouse and Sculpt Mobile Keyboard-- thanks to extra Windows 8 functions and a change of Windows logo.
