Before I take a serious stance in this discussion, I'd like to honestly know how much it costs to produce each marker (e.g. Ion/Spyder/Tippy/whatever). If it costs only, say $80 to produce one marker, and all the rest is profit, all the Ion really is doing is cutting some of that profit. Now granted, other pb companies are going to take a hit on this, but wouldn't we agree that it would provide incentive to produce/release better or more appealing products at lower cost? Appealing products = large sales = regain profit. All that results from the Ion then is consumer benefit, in this manner of thinking.
/or maybe I'm just way off, but that's my OPINION
