I gotta say something here. This poll is stacked and unfair.
You have four out of five poll statements that support the existence of a demo and only one against it. To be
FAIR the poll statements should be evenly listed -for and against.
Here are some examples that should be added:
***I'm against a demo because Matrix Games is against it.
***I'm against a demo because it is a bad business choice for such a small company as Matrix. (It is a LOT of work for very little $$$ return.)
***I'm against a demo because it takes away valuable time from the development team while they are developing a great game that I want yesterday.

(Basically, it is a distraction.)
Add something like those statements and it will be a fair poll that can be taken seriously.
Denny, we all know your position about a demo. We've seen it ad nauseum elsewhere.
