New gadget: 3D-mouse

I've got a new gadget, a 3D mouse.
This mouse must be used along with a normal mouse, so I will use this one with my left hand.
You can pan objects in X and Y direction, rotate in X-, Y- and Z-direction and pull the knob up-and-down which will be used often for zooming.
It also is usefull in Photoshop and Google-earth and tried it in the office using Autocad.
