I'm looking forward to seeing how iCloud is implemented. One of the more exciting recent developments in tech for me has been the convergence of various devices into a unified system where data and applications can follow the user from desktop to laptop to tablet to smartphone. I see this as a significant shift from individuals being tied to devices to devices being tied to individuals. Hopefully Apple has made this even more seamless than it is now, and the effort to synch all your "stuff" will be so minimal that to call it an effort will be a stretch. One thing I would have liked to see is Siri implemented, although, in all honesty, it would be more of a toy than a necessary tool on a laptop or desktop. It would still be cool though!
