모바일 단말은 인간과 가장 친밀한 관계를 가진 정보기기다. 그 중 핸드셋은 전세계적으로 가장 많이 사용되고 있는 정보기기로 세계 IT 산업의 원동력이기도 하다. 핸드셋이 보급되기 시작한 지 10여 년이 지난 현재 핸드셋은 발전된 하드웨어의 탑재와 다양한 기능을 융복합하는 진화를 경험하고 있다. 이제 핸드셋은 전화 통화를 제외하고도 수많은 통신 수단의 중심이 되었으며, WiBro, HSDPA 등 무선 네트워킹의 진화와 더불어 이런 현상은 계속 진행될 것으로 전망된다. 한편으로는, 하드웨어의 사양이 높아져 탑재되는 소프트웨어의 복잡도가 늘어나고 있어, 스마트폰의 OS는 수 년 전 PC에서 사용되었던 수준이 요구되고 있다. 본 고에서는 핸드셋 산업의 현재 상황을 분석하고 스마트폰의 OS의 연구 및 개발 현황을 살펴보고, 향후 스마트폰의 모습을 조망해 본다.
