For scale, the iPhone Duo is taller than a credit card (85.6 mm). Beside a 330 ml soda can it appears shorter and squatter. It fits a pocket or small pouch more readily than a passport.
At 254 g, the iPhone Duo sits in the expected range for something you hold and use one-handed. It is light enough for extended one-handed use without wrist fatigue, though a jacket pocket is the practical limit for carrying it around.
Fits in larger pockets or jacket pockets only.
Best used with two hands for full screen access.
