The first version known during development under the code name "Pegasus" featured a Windows-like GUI and a number of Microsoft's popular apps, all trimmed down for smaller storage, memory, and speed of the palmtops of the day. Since then, Windows CE has evolved into a component-based, embedded, real-time operating system. It is no longer targeted solely at hand-held computers. Many platforms have been based on the core Windows CE operating system, including Microsoft's AutoPC, Pocket PC 2000, Pocket PC 2002, Windows Mobile 2003, Windows Mobile 2003 SE, Windows Mobile 5, Windows Mobile 6, Smartphone 2002, Smartphone 2003, Portable Media Center, Zune, Windows Phone and many industrial devices and embedded systems. Windows CE even powered select games for the Sega Dreamcast, was the operating system of the Gizmondo handheld, and can partially run on modified Xbox game consoles.
