Windows Live Messenger for Zune HD

The release of Windows Live Messenger for Zune HD is interesting to me for two reasons. One is that I think instant messaging has lost popularity over the last several years, with text messaging, Facebook, and Twitter taking its place. The second reason is that I think that the Zune HD is an awful device for running apps, particularly apps that require text input because the screen is too small and the keyboard is probably one of the worse on-screen keyboards that I have ever tried.
