Without watching the video you can see where its going to go. The App Store can be seen as a quality app marketplace with strict guidelines and moderation whilst the an app marketplace on your android phone can be full of danger, the unknown and clutter.
This very short video from Apple nails this exact scenario to the core. Being short you can take it all in, its simple and perhaps can be seen with some humor. A definite shot by Apple in saying the App Store is the best app store.
In the past there has been ads by Samsung mocking those lining up at an Iphone launch, using Apples adapters and no waterproofing but this time its Apple firing back. The direction is of course along the lines of the traditional premium Apple quality and design. With Apple taking advantage of androids cluttered and murky app store alternatives.
