It's clean, safe, and efficient. There are lots of entertaining things to do. Kids can drive cars; adults can wear goofy hats with impunity. There's a parade every afternoon, and an underground medical center in case you get sick. All of this is possible because of central planning. Every restaurant and store on Disneyland's Main Street is approved in advance by Disney. Every employee is vetted by Disney. Disneyland wouldn't be Disneyland without central planning.

The iPad, like Disneyland, will continue to be an island of central planning in a sea of decentralized innovation.
