Precise framing, long exposures, difficult positions, precise panoramas, waiting for the right lighting. And yes, there is a difference between base ISO and high ISO, but there is also a difference between slow and fast shutter speeds and large and small apertures.

I use a tripod frequently, and yes, they are necessary for my landscape shooting.
For snapshots, they are not.
jcboy3 hit the nail on the head, IMHO. My best landscapes were shot with a tripod. (My U-line with a Gitzo head did the job, but I recently switched to a much lighter and easier to use carbon fiber Manfrotto tripod and ball head. Worth every penny.)
