Motorola MOTOMAGX - linux based OS - Building on the global success of Motorola's earlier Linux-based platforms, MOTOMAGX incorporates best-of-breed open technologies to deliver new levels of openness, flexibility and support for third-party applications on Motorola mobile devices. The MOTOMAGX platform supports applications developed in Java ME, with plans to introduce development environments for both WebUI and native Linux applications in upcoming releases. The first products based on the MOTOMAGX platform are the MOTOROKRTM Z6, MOTORAZR2 V8, MOTOTM U9 and the recently announced MOTOROKR E8, which won CNET's "Best of CES" award in the cell phones and smartphones category. -- LIFESPAN SUMMER 2007 - OCT 2008
