Looks like Sandio chose CES as the venue to officially announce its "3D Internet Mouse," which first sneaked onto our radar earlier this year. It's geared to handle 3D navigation -- whether that's flying around Second Life or manipulating 3D models in Google SketchUp.

According to the company's announcement, the 3D mouse features an intimidating sixteen programmable keys, and while Sandio explicitly says it wants to enable Second Life users to move in various directions, fly and crouch all with one hand, leaving the other free for keyboarding, it also suggests that using the mouse can provide PC gamers with "some unfair advantages."

Reflexes are key in games, and I'll leave the profusion of snarky jokes about one-handed Second Life users to other sites. The Sandio 3D Internet Mouse is currently available in the U.S., Canada, Japan and China, and at eighty bucks, is a relatively pricey peripheral -- is virtual world dexterity becoming that important to users?
