Yeah i have to use Photoshop CS3 all the time. With all the tools and such you have to know to use it, Sketch up was a cake walk for me. It really isnt that bad. Doing an angled back to a box took me a sec to figure out, but there are a few quick and to the point demo out there to help in the areas that may be a bit harder to figure out. For a lot of designs its not needed, but it is very cool to be able to see the project in 3d.
