On their own the features are interesting, but it's the message behind the features that really caught my attention. Together, these features amount to a very clear benefit: The removal of limits to how you communicate with others remotely.
Think about it: Every other app or device we use for communication requires a certain category or format of that communication. Phones are great for long-form audio. SMS is great for text and sometimes images. Other messenger apps are great for short form messages and transactional conversations. But before this release, no single app or device optimized for all the ways humans communicate: long form, short form, audio, video, text, photo, and drawing.
Which means that Snapchat, for now, is actually pretty special.
