| Bottom line | Microsoft's ergonomic keyboard is comfortable to use and supplies a few useful extras. | Though it may not offer much relief from clinical repetitive stress injuries, the Microsoft Natural Ergonomic Desktop 7000 will satisfy users who want a slightly more comfortable keyboard and mouse than the one that came with their computer. | The Logitech Wireless Keyboard K350 stands out for its comfortable ergonomic touches, an easy learning curve, affordable price, and unique Unifying connection. We have minor issues with the placement of the media controls, but heavy typists will appreciate what Logitech has to offer. | The Microsoft Wireless Comfort Desktop 5000 is a solid keyboard and mouse combination with a bevy of customizable buttons that make it a no-brainer to use with a home theater PC, but the asymmetrical button layout on the keyboard requires time to learn. If you're looking for a more ergonomic desktop set and willing to put in a little work, the Wireless Comfort Desktop 5000 will serve you well. | It's always worth reexamining technological features we take for granted, but even if you like Microsoft's new approach to the spacebar, the Sculpt Comfort Keyboard needs some streamlining before it merits a recommendation. |
