well I could see that having what I said could be useful in that you could enter the program, use your dvd of the os which we should basically all have anyway. now with the program running I could create a preset if something were not to work I could send the preset file to someone who could open it and see how to tell me to fix it. thats just one reason I can think of for not having to commit resources until I am sure all my choices are correct. basicly I don't like the idea of having to copy GB's of data just to look around in the program. even the post give me the ability to preview before I commit.
