What is amazing about Rhino is that it is very easy to pick up. And with a few tricks, anything you can imagine can be modeled. It can be intimidating at first but after a while things get much easier. What is important to know is that there is no single way to execute any given task. The McNeel web information on each command is also great and pretty informative. They have little videos of every command. I have not seen such detailed explanations elsewhere.

Some parts of the interface are a bit clunky. The infinite possibilities can prove to be very daunting. Certain commands have too much of a crossover (for example, UnrollSrf and Smash - still don't know the difference between these). The biggest disadvantage (which may be an advantage for some) is that Rhino is not a standalone product. By this I mean, knowledge of associated software is often required - like VRay for Rendering, Illustrator to set lineweights for linework, Grasshopper for complex parametric geometry, Revit for BIM. Furthermore, programs like VRay aren't the best when used with Rhino - Chaos Group focuses more on their Max plugin Review collected by and hosted on G2.com.
