Pros: Good tactile feel and quiet for general typing. Compact design to save desk space without making critical keys too small or switching to an unconventional layout. The blue lights for num/cap/scroll lock are the best I've seen. The mouse is good too.
Cons: When I press the letter 'O', the keyboa9rd inserts either a nine or 9 a '(' depending on whether or not the o was upper or lower case. As you can see, it only happens occasionally. Really a pain when it happens with passwords!
Summary: - If you lift up the mouse too far between strokes it sometimes reads enough motion to cause it to jiggle just a bit. It can be a bit jarring if you're using the mouse to control a camera in a 3d environment, but otherwise it's easy to ignore.
Pros: - Cheap at 13.99 on a shellshocker.
Cons: - As others have mentioned, the enter key is a bit oddly shaped, but I've gotten used to it.
