Developers Setting Expectations Ahead of Mac App Store Launch
For the most part, Nigrin's results show that iOS developers moving their apps to the Mac App Store are looking to maintain their existing price points, which frequently fall in the $1.99-$4.99 price range.
Why does a 1:1 adoption of the price on the Mac seem so natural for iOS devs?
For once, Apple made the code re-use for a native Mac app very straightforward. Every dev I talked to mentioned porting times of less than four weeks. Which were mostly spent on all types of adjustments, like keyboard and HD support. Also, graphical assets for mobile games are typically originated at a much higher resolution anyway, as everybody in the iOS world needs to prepare for a foreseeable future of HD displays. The point is, if you already have the assets and re-creating a native Mac app is relatively low-cost, there is no immediate pressure to go with another pricing model on this platform, if the reward could be an early (chart) success.
