The Windows Blog has some interesting information about the Windows 7 logo scheme.  For those who don’t know about it, which is probably most people, the logo scheme helps to clearly identify devices that give the best experience with Windows 7.  The networking changes in Windows 7 are superb and it’s even easier to set stuff up quickly and most importantly securely with Windows 7.  The logo scheme gives you the guarantee that everything will work perfectly, including things that have traditionally gone a bit awry such as UPnP or discovering other devices on your network.

Also worth noting is that any network device that support media playback, like TVs and network speakers with the logo will be fully DLNA compliant too so there’s a good chance they’ll work with other components of your DLNA setup.  Logoed devices will also appear in Device Stage so you’ll only have to go to one place to configure your devices.
