Justin Williams on the new version of Elements for iOS 7 and the “Customization Pack” he introduced as an In-App Purchase:

I’m approaching this how you typically buy a car.

When you walk into a dealership, you may know that you want to buy a Ford Focus, but there’s not just a single Ford Focus. There’s the base model the lowest possible price, but you can enhance the car with additional add-ons and upgrades to make it the car you want. That’s how I am approaching traditional software for the forseeable future.

That’s an interesting way to put it, and I think that we’ll see several developers adopting (or switching to) this strategy in 2014.
