Sure there are benefits. The keys are backed up remotely and you have access off-premises. If anything goes wrong, presumably you can call up tech support and they can access the system without your opening ports on your router or messing with a firewall. It could make administration (and reliability) much better. They may not be benefits that you want, but they're the benefits that Lockitron are stressing. (Personally, I'm happy with a key and, FWIW, my parents don't run their own control panel on their Vodafone local cell-network box - they call up the service people and they access the box remotely. So I can happily agree with your comparison too, if you like.)
