alternative OS experience (all but windows)
Many developers usually package their applications in Mac OS X disk images (.dmg) because it is a simple and safe way to transfer data over the internet. By storing your applications in a disk image, you get for free: * compression * self-extraction * license agreement dialog
Creating a disk image manually, however, is a waste of time, especially when releases are frequent. Even if it consists in a quick drag and drop! Moreover, you have to pay to get a dmg builder application that allows to add license agreements.
