Xbmc
XBMC is absolutely brilliant. I use this as my dash.Its really easy to update now as well as it now comes with an xbe shortcut that you just put on your c drive and name it something that your bios boots.
When you want to update it you just delete the xbmc from the e partition and then just dump the new version in. THe shortcut always find the new version,......sweet. Just updated it this moring.
Plus with all the scripts you can download as well.THere even a scipts installer now...... am lovin it.
