to all the maudlin comments about how sad it was that he was NOT devoting his time to saying goodbyes and preparing to shutdown.
just maybe he had already spent time saying goodbye to those he really cared to say goodbye to, he had already prepared something for his family in the many numerous in-depth interviews he did for the book, and was there in the home everyday now.
just maybe that since he had everything in order by then and like any restless brilliant mind he hadn't turned off the all that experience, obsession, passion that had driven him to where he was, just perhaps the best balm for his mind he could have is Tim coming over to discuss the future details. Jobs was always obsessed with details and future plans (just look at his presentation of the plans for the new Apple HQ at the town meeting a few months ago). What better than to lose yourself in your passion for a timeless moment and forget the inevitable for a little time.
I can't imagine he would have any desire to lay around ticking off the time while family hovered over him wailing.
