I just skimmed the long video..

The good: auto-refreshing preview of HTML page upon save

The bad: no auto-end-brackets or end quotes as one types (ironic, considering the editor is named Brackets)

I am sure that the talented Adobe engineers will make this editor a major contender for Sublime and Textmate in the future, but at this point, I think the stunning attribute in the post title is a bit link-baitish. I'm looking forward to watching the editor develop into a mature product!
