"X-Box represents Microsoft's second attempt to crack the game console market. Microsoft once tried to drive its Windows CE operating system deeper into homes by partnering with Sega Enterprises on its Dreamcast machine, but the Microsoft-Sega deal on Dreamcast has proven to be less than successful because Windows CE has meant little to either game developers or the consumer electronics market in general. Game developers continue to write video games to Sega's proprietary platform, rather than to Microsoft's Windows CE API. No other consumer electronics vendors have positioned Windows CE as a must-have operating system for their platforms. "
