Excerpt from a Cringely Apple WWDC perspective
What this requires from Apple is a bold move that Microsoft would never make: Jobs is going to sacrifice the Macintosh in order to kill Windows. He isn’t beating Windows, he’s making Windows inconsequential.
Having been shown the way by Apple, I expect Google to shortly do the same thing, adding automated backup, synchronization and migration to Android and Chrome.
Both companies will be grabbing for data, leaving Microsoft alone to defend a desktop that will soon cease to exist.
