@thread
It's nice to read all the opinions and experiences in this thread, quite a variety

I will apply some statistical analysis to the results once the poll runs it's course at the end of the month. A stats professor at my University has written an excel spreadsheet for me that will do this.
He said to me if you estimate a total population size of 2000, 5000, or 10000 possible users, the poll has a plus or minus accuracy rate of 9.5%.
Extrapolating those numbers out based on the population estimate could give you an estimate of possible sales.
For example, currently the poll has 38% of respondents saying "Yes!".
38% of various estimated population sizes is:
For 2000 Users: 760
For 5000 Users: 1900
For 10000 Users: 3800
The variance is plus or minus 9.5% as I stated.
At least that is how I interpret what the Professor has said to me. But once the poll is finished I will ask him exactly how to interpret the results and I can even post the spreadsheet here.

I'm by no means a stats expert so I could be totally wrong.
