Specifically, high-profile placements (cover, lead pages) by IBM and HP?
Don't forget too that this was the week of LWE, which is going to see a concerted publicity push by a number of firms, though given the reports (I didn't attend) from LWE, there were a number of companies which were surprise no-shows (Agenda) or were only dragged out reluctantly (VA).
Spending a couple of days in SF though, the number of IBM astronaut and Peace, Love, Linux ads plastering the street is quite noteable. That US$1b campaign includes a large marketing component, I'll wager.
