Survey: Why Do You Buy CAD Software?

As promised, a survey to explore why users buy a particular CAD software has been created. Please give your input at http://www.surveymonkey.com/s.asp?u=891102592287. You can see the results as the survey progresses by clicking on the "done" link at the bottome of the survey.

When I initially suggested factors that influence a buying decision in a previous post, I neglected to mention cost. A revealing oversight, perhaps? We shall see.
