My 360 currently gets most of it's use from being a Vista Media Center Extender. I have a dedicated computer with two wintv-pvr-usb2 http://www.hauppauge.com/pages/produ...a_pvrusb2.html
for recording cable. Plus another dedicated computer for Windows Home Server for movie/media/music streaming http://www.microsoft.com/windows/pro...r/default.mspx
. In my MCE box I only have 200gig for recording tv onto, while my WHS box has 1TB of storage. It is extremely nice to be able to watch the shows you want when you want, and stream all the media you have seamlessly to your tv/stereo though a 360 or xbox.
