A friend of mine works a lot with CAD programs like AutoCAD or Autodesk Tools. To his birthday I thought it would be a good idea to present him with a graphic tablet for 3D applications. Unfortunately, I'm very unexperienced in this field :-) so my questions are 1) is it really a good idea and 2) what are important characteristics of such a tablet I have to consider when I select one. I could image resolution, and size?
I would recommend a 3D mouse instead of tablet. I have both and 3D mouse is better for 3D applications such as Autocad.

In this case (as a gift), consider their SpaceNavigator which is an affordable model.
