If you don't like it, don't buy it. Capitalism (read this if you are confused:
http://en.wikipedia.org/wiki/Capitalism) is that simple. Take your money elsewhere if you are unhappy with the price.
If someone thinks it is worth $15.99, they'll pay it, otherwise, they won't. If not enough demand accrues, Beejive will most likely lower the price to meet demand.
It amazes me the iPhone has so many whiners when it comes to application price. When I was on BB, I gladly would pay $50 for an app that did what I wanted. Just like I will pay the $989 for Photoshop at Newegg if in fact that is the app I need to do what I want.
I sometimes think the iPhone had a better userbase when it was $499. Scratch that, I always think that.
