Yes, export OBJ with N-gons. MoI does an excellent job of meshing for C4D.

The reason I found the tablet harder was partly because it has so many curves and rounded edges, but mostly because I had a really hard time modelling the groove where the upper and lower halves of the plastic tablet join. I could get a groove down the side, but making it continue under the tablet was very difficult (in fact that model doesn't do it, but you can't see so...).
