The only complaint I have so far with Sketchup is I cannot seem to get the stamp tool to work properly. The stamp tool allows one to place building onto interesting 3-D terrain more seamlessly by raising the proposed land to meet the building, much like a foundation. I believe this limitation has more to do with my limited computer processor speed than with the limitations of the program.
I wanted to point out two resources I found to be of use/example of what this program is capable of.
Mr. Aidan Chopra is the author of Sketchup for Dummies and has 62 tutorial videos on youtube that cover material not offered on the Goggle Sketchup tutorials.

TaffGoch shows how to quickly import 3-D terrain into sketchup, develop contour lines, and texture the terrain as well.

Attached is imported 3-D terrain that takes only 30 seconds to create and then import for us in Sketchup.
