Because I am a nerd and I want to develop some games using the XNA for the PC and the 360 when it comes out, I went down to the local GameStation and bought a cheap second hand Xbox 360 controller.
I have just been testing the programming model with it and all seems well. I can sesne the pressure on the triggers and all that stuff using the XNA.
One thing that I did notice is that I couldn't install the Xbox 360 Controller Common driver for the Windows XP. However I did find that XBCD drivers worked for me and it works with the XNA. You can find the drivers here [http://xbcd360guide.50webs.com/]
I presume the download is okay, nothing scary has happened, although the design of the site doesn't inspire any confidence.
