You'd be surprised how many people do actually use it for dedicated storage applications. With the major backer for OmniOS some (including me) have been moving over to ZoL as a preference. It's a real shame not to have it more integrated otherwise though in less dedicated applications. It's really hard to go back once you are used to zfs send/recv, transparent compression, etc.
