I suspect, Wade, that your preferences will not be met by the current (profitable, successful) incarnation of Apple. There's a reasonably reliable correlation between the presence of Jobs at Apple, and Apple making money. The Newton was made at a time when Macs were beige and folks like Michael Dell felt empowered to say things like "Apple? If it were me, I'd shut it down and give the money back to the shareholders" (or words to that effect). Those days are gone, and I find it frankly inconceivable that an organisation that is as effective as Apple would not put in place a culture and hierarchy that continues to execute on the vision.
