WWDC is like Christmas for Apple developers. We give Apple our list throughout the year via reports and blog posts and the like, and on one special morning Apple gives us a bunch of presents in a new version of the OS.
From a user of Apple products perspective, the one I really want is apps for Apple TV. I want to get rid of more components under my television and hopefully opening the device to apps would let me do that.
Justin Williams over at carpeaqua created a post with everything expected of Apple this year for the Internet to be happy. It is an amazing list. Take a minute to read it. (My UIWebKit one, by the way, is not on it so, Justin? Please add #51.)
