XYZ Computing has posted a review on the 3Dconnexion SpacePilot 3D Design Tool

Designed in a similar manner to Logitech's diNovo line of keyboards, the SpacePilot is sleek, sturdy, and definitely feels expensive (and, at $450-ish, well, it pretty much is). The central focal point is the SpacePilot's "controller cap," a two-inch diameter, rubberized knob. The cap is somewhat motile, and allows for pushing, pulling, twisting in any direction. The SpacePilot also features twenty other buttons, and an LCD panel that displays context-sensitive information related to the use of the SpacePilot. I'll get to these in a moment.
