I entered a drawing to win a copy of Rhino 3D a few years ago and was
overjoyed when they called. Unfortunately, it wasn't a winner's call,
it was notice that I had not won and an attempt to sell me the
product. It looks like a great program, but I don't do enough to
warrant the price. OK, now I'll read on.

They would have done far better long-term to
have given you a copy. They would have made
plenty of money on support and options over
the years.
