THESE CLEVER APPS SHOW OFF THE IPHONE DUO'S POTENTIAL

Summary from the TLDR Design newsletter

Developers are creating playful apps built around the iPhone Duo's folding design. Deck-Man turns albums into virtual cassettes, letting users load a tape with the phone open and close it to listen, complete with mechanical playback sounds. TypeDraw uses the fold as a notebook cover, with customizable paper, drawing tools, and fonts based on the user's handwriting.
