Tonight we were introduced to LinuxMCE, a slick Computer Media Interface. We will update this post with further details, but what was really novel was to see a WiiMote configured to control LinuxMCE. WiiMotes cost about $30 USD versus $100 USD for an equivalent Bluetooth Remote Product.
Another good programme to consider is XBMC.
Lastly, the very impressive PS3 seems to do everything under the sun in Media Centre Entertainment, including the most powerful gaming console around, for $300 USD.
