Designer Andrew Kim has cooked up a concept smartphone for HTC dubbed the "1" that makes the company's current offerings look, well... last generation. The device, built from a brass housing (coated in silver) eschews the phone-maker's recent crop of fairly standard looking mobile devices for something decidedly more sophisticated -- and cans the familiar Sense interface in the process. Not only is the shell of the phone rethought, the new UI (Sense mono) takes a cleaner, more thoughtful, high-end approach as well, joining Synergy like functions (combined messaging) with a Helvetica heavy interface that looks streamlined and mature. Some notable features of the hardware include stereo speakers (located at the top and bottom of the phone), a kickstand which is actually the bottom portion of the casing, and the lofty concept of a built-in UV light which kills germs on the surface of the phone while you charge up. As far as concepts go, this is one of the finest we've seen, so hit the source link below and take a look at the full spread.
