The XBOX360 is already an attractive media center extender, but it indeed lacks the built-in high-definition player and a more voluminous hard drive. Not having a native wireless interface (instead, one would need to buy a pricey add-on that plugs into the Ethernet port) is also a pain, since more and more people integrate Wi-Fi networks, more than they used to and have come to expect this functionality in everything. Righteously, too. Another thing to look forward to, imho.
