How often does your existing display adapter get updated with new features?

You think that because that's what the fine Apple iWork apps cost, but keep in mind that they normally sell that as a package, and now each application costs $9.99. So the total price for many people will actually be $29.97, 38% of the cost of the Mac OSX version.

Now that the "iFart" craze is over, expect to start seeing more specialized apps selling at higher prices. "Things" is already about $20 and they are a top grossing app.
