Steve Jobs is now doing fine medically, operating much the way he did before his recent liver problems took hold, say Bloomberg sources said to be "close" to the Apple CEO. The major issue is believed to be weight, as Jobs remains unusually thin, to the extent that he allegedly discusses the problem with acquaintances. One former Apple executive observes though that Jobs has actually intensified work since returning. Three other Apple workers comment that he has been seen around the Cupertino campus more often, for instance taking meals in the cafeteria.
