I like the fact of having DNS. This way, if I wan't to access a directory, I don't have to type in my old URL and if people wan't to link to a certain page, they can't use the .tk. Plus, they have a popup. If it wasn't for these things, I would still have a .tk. uni.cc provided DNS control but they don't anymore, if they did, I wouldn't even have a .net domain.
