> App bundles are so much better than whatever MS has in store
Hm? The dmg files that you have to double-click on, manually drag into your app folder, then manually unmount from the desktop? Why do I still have to do all that busywork in 2015?
App bundles are folders with a file extension and a binary at a specific place. Folders that you can double click (and then some!) That's pretty great.
DMG files are a way to ship app bundles (or other files). They're basically images with compression and checksumming added on top (I think). Images are useful (compared to, say, a zip archive) because you can mount them (e.g., over a network). That's useful for all kinds of sysadmin-y things. (Compression and checksumming are obviously useful as well.)
