Apple's sneak peak at Leopard at WWDC was received with mixed feelings. On one hand there were some that felt that the new features were underwhelming, while others saw them as great, necessary improvements that will make everyone's life easier. Without a doubt, the new features introduced are not revolutionary in themselves, but then again in terms of operating systems there is little to no revolution to make until there is some new significant breakthrough in technology. However, while the new features are not revolutionary in themselves, the OS X approach certainly is.

With every new release, the differences between OS X and other operating systems become deeper. OS X is slowly becoming a holistic environment that mimics the way the human mind processes information which is all intertwined and interchangeable. Meanwhile, Windows and Linux are stuck in the 'tool' mindset simply offering the means through which to use other tools, but never moving towards creating the links between everything that exist in OS X. Of course, Apple is in a special position where it can afford to do this and drive the evolution of their platform, whereas the competition is stuck in the reverse situation where the platform dictates to them.

Yes, Leopard might not seem like a huge leap, and the features taken individually may be lackluster, however, as a whole, it is a revolution in the making, and several years down the road, the workflow will be so unique and compelling that it will make other operating system look as outdated and primitive as the text based ones.
