Our friends over at Technologizer posted this interested video of a usability study featuring the iPhone 4, a Samsung Focus running Windows Phone 7, a BlackBerry Storm and an HTC Thunderbolt running Android. This study, which as organized by University of Pittsburgh professor Dennis Galletta while teaching a summer course at Harvard, examined how novice users would perform a number of basic phone features like calling, adding contacts and sending a text message.
