Does it ever make sense to use Cassandra on a single node for anything but dev/test?

I am under the impression that Cassandra's performance comes from its distribution capabilities.

It does not make sense to only use 1 node. It's not designed to be a fast 1 node DB.

In fact for most dev I use 3 nodes on my laptop, and most of our "unit" tests are multi-node as well (closer to integration tests by most measures).
