The main motivation behind the XFPS 360 adapter is to enhance the First Person Shooter experience. The company who manufactures the XFPS, XCM Technologies, feels strongly that the Xbox 360 controller is completely unsuited to playing FPS games and therefore allowing your fingers to use a keyboard and mouse (as PC gamers are undoubtedly used to using) you will be more accurate.
The adapter is relatively unassuming with a plastic shell that can sits on any surface, although the black color choice is a bit suspect given the cream exterior of the standard 360. There have been some complaints about compatibility issues, namely the lack of detection for some mice and keyboards. However, the PS2 controllers work well and are plug-and-play detected.
