Right exactly. I think from the perspective of devices (say your laptop) it looks pretty similar to the current system. You give it the IP address of a "DNS server", but now it's hitting an Ethereum node who is doing the DNS lookup. There is danger there that the node could lie about the state of the blockchain, so it does need to be trusted. The paranoid can always run their own node and be 100% sure. I do think you could expose the same interface as traditional DNS but backed by the registrations in the blockchain. There are browsers that will resolve Ethereum Name Service domains today, but I'm not sure how that's implemented (probably lookups on a public ETH node). The important improvements IMO are on the registration, transfer, renting of the names rather than the lookup side which doesn't look dramatically different except that other code running on the blockchain could do the lookups too.
