As Tim Cook embarked on the developer section of the keynote at WWDC, it might have been easy for end users to disconnect. But, if you did, you'd have missed out on two fairly solid updates: developer app bundles and (finally) video previews. Now, developers can combo their apps and sell the bundle for a discounted price should they choose. Likewise, previews allow developers to give us a better taste before we buy. If you happen to dabble in developing yourself, then you might also be relieved to hear that TestFlight is now officially part of Apple's developer setup, too.
