I'm using the pro edition trial (soon to be full version) to look at geomorphology. It'd be really handy if I could select custom colour ramps for colouring the surfaces, control the lighting position, and apply terrain exageration. I can (once I have the full version) do all of this by exporting to ArcMap, but I don't imagine they're particularly hard editions to the software and they'd be dead handy.
Cheers,
Alex
