I am just blown away at all the work, time and effort Apple puts into OSX, iOS, now the developers SDK, etc. I think most of this is missed by the general public as the only thing they are looking for is the new gadget they can go buy and don't realize the tremendous things Apple does behind-the-scenes to make all of their products work so great.
*However, I still don't believe Tim Cook quite understands that Apple is missing the Magic of Steve Jobs and his famous "Oh, one more thing..." Even though today was stock full of amazing new features, I think they needed to announce something tangible to keep the excitement going. Guess it will be 4 more months of rumors...
