Looking for ergonomic keyboards or other input devices that won't break the bank? An article in Popular Science takes a brief look at 5 options: the Wacom Intuos3 Pen, the VKB Virtual Keyboard, the Microsoft Wireless Optical Desktop keyboard, the Logitech Cordless Desktop LX 501 Keyboard, and the FrogPad.
According to the article, Key Differences, "More than half a million people every year suffer from repetitive stress injuries. 'The risk of injury is four times as great for people who spend six hours a day at the computer as it is for those who spend less than one hour a day.'"
If that sounds like you and you haven't taken a good look at your work (or play) area in regards to ergonomics, maybe it's time.
