No sorry, the fact something sells is only an indication that "some" peole are willing to pay for it. If a wifi adapter is priced at $500, i'm sure a couple thousand people would buy. Therefore it would selling, and by your definition, $500 would be the right price.
The idea that just because something 'sells' it's the correct value it ridiculous, it may sell 10x's more at a lower price, indicating the lower price was more along the lines of being the correct value.
Joe already answered this question.
If you want to be pedandtic about it:
"As long as stuff sells with the volumes that MS has targetted, the price is right."
I assumed that bolded part would be implicitly understood.
