I've used otterboxes before for my iPod, and they'll take anything you throw a them... if you don't mind carrying a brick around. So the otterbox 2000 is a good fit for the n800?

And also, I assume that one cannot use the camera while in the Strongman case, or the Otterbox for that matter?

How do you charge the n800 while it is clamped down in the Strongman case? Or access the external memory card? Can the device be taken out easily enough?
