Jobs' first task when returning to Apple was obviously to return the company to profitability, which he has done very well. His second task was to re-establish Apple in the industrial design space, which he has done an excellent job of. My opinion is that his third and most important task is to re-ignite the old-school Apple soul (its software), a soul that is oddly missing from its current Mac OS X approach. Apple needs a new platform, one that re-defines computing for the next 20 years, not one that celebrates and brings forward all of the warts and compatibility baggage of the past 20. It is my belief that if Apple is not already heading down a new path, one it will undoubtedly have to pursue parallel to its Macintosh efforts, its longevity is uncertain. The industry needs a leader that is unafraid of taking chances, making radical software architecture changes, creating rich and dynamic platforms for developers and users alike to build on; risky moves are the only ones that gave Apple the "head-start" it briefly had and ultimately lost in arrogance and internal struggles; it's time to raise the pirate flag once again and break itself out of the prison of old ideas, expectations and legacy compatibility it still appears to be obliviously constructing.
The Newton was a ground-breaking stake for Apple because it was a new platform geared towards many of the problems that remain today with regards to data representation, collection, storage, and exchange. Newton's runtime environment was highly dynamic, prototype-based instead of class-based, geared towards the storage and retrieval of small and larger pieces of information (notes, media clips, URL's, ideas), but never really took full advantage of the Internet. The Internet is a vast soup of all these disparate types of information and today's hierarchical file systems, relatively static and outdated programming languages and runtimes and mirrored desktop user experience are not geared towards creating, authoring, sharing and exploring these types of data. Newton is one of Apple's greatest assets. I dearly hope that Apple has not abandoned these technologies altogether.
