@DeathByVisualStudio: At least give the user a fair chance to see if it works for them. By that I mean don't give it to them and tell them "you'll hate this, let me know when you want me to fix it". That just skews the sample. Oh, and let them use it for a significant enough period of time that they have a chance to actually get used to it. While they might be intimidated by technology, they are adults who are capable of learning new things.
