Is bin Laden still with us?

I haven’t followed news about bin Laden too much in recent times, but his name is popping up now in light of the Christmas cockbomber escapades (sorry, couldn’t resist).

A CIA guy who was on the latest Charlie Rose mentioned that they are still looking for him, and I heard a similar mention elsewhere (maybe from a congressman on TV, I don’t remember).

Anyway, is he still alive or is he like a modern-day Spartacus?
