It's great with sketchup and google earth. And $50 is great compared to the $300-500 models. I hear if you're going into CAD or 3d design big time, the more expensive ones are worth it. However, for my
minor use in sketchup, this model is perfect. (I've pictured a second mouse used to do the same things, but these models are probably more intuitive and 6 dof vs a mouse's 2.)
It doesn't register as a joystick or other
game controller, though. So to use in mame some source edits need to be made.
Looks pretty easy (copy and paste one function, edit one to three lines, and call that function after the function-that-was-copied function call), but I haven't tried it yet. And other games, it probably won't work either. Looks like it'll work with just the apps that it has drivers for.
