"It's no longer possible to write a single app that takes advantage of the full range of Mac OS X features. Some APIs only work inside the Mac App Store. Others only work outside it. Presumably, this gap will widen as more new features are App Store-exclusive, while sandboxing places greater restrictions on what App Store apps are allowed to do." Anybody surprised by this, here's the clue stick. Please proceed to hit yourself with it.
