Quiz: Planet of the Apps: A Hand-held Revolution

Just as "Seinfeld" was a show about nothing, "I Am Rich" was an application that did nothing. When the app was launched, the screen displayed a single button. When the user pressed it, an affirmation would be displayed on-screen that said "I am rich, I deserv it, I am good, healthy & successful." The misspelling of "deserve" was intentional, as was the asking price of $999.99. "I Am Rich" was removed from the App Store the very next day after its release, with a grand total of eight people who actually bought it, one of whom did so by accident.
