This is like that "Friends" episode when Joey wants to climb Everest but its $60,000 so he wants to rent a film about Everest and then they end up renting Die Hard.
Exactly! If you have exactly $500, you can fly one way to Paris and potentially starve to death, or you can buy a nice iPad and enjoy the city from the comfort of your own couch!
Let's be honest: there's no substitute for going to the actual place. However, this is a great way to get a visual orientation of major cities before visiting. Agree that cities will likely promote this in their apps.
