Tablet

I believe that any tablet with a 4.1 ADI driver is supported in addition to
those that are SummaSketch compatible.
However, because of some glitches with the use of "tablet mode", you are much
better off to set up your tablet in "mouse emulation mode" for 3DS. Switch to
tablet mode only when you need to digitize a shape.
If you are looking to buy a tablet, also consider those with pressure sensitive
stylii. Even though they give no immediate benefit in 3DS, it is very helpful
if you use painting or image retouching software.
