This has been asked many times, but invisible; it has so many more practical uses
You're right about invisibility having a lot of practical uses, but not being seen has downsides too. You really need to be careful about where you are because people can't avoid what they can't see.
Despite the awesomeness of invisibility, I'd rather be able to fly. Its one of those things that I've always wanted to be able to do.
