For GUI rendering time on Android emulator, with the same amount of memory at 512 MB and same hardware configuration, Windows XP Professional is faster than Windows 2003 ServerFor Windows Vista with 8 times the amount of memory at 4 GB, the performance gain in rendering time is very minimalSo in conclusion, Windows XP Professional is the ULTIMATE platform to develop Android applications since it renders quickest therefore the total time spent on coding, debugging will be relatively minimal compare to other platforms
