Well to be honest JD, I've never noticed it on my PC before. I've just now set it up, and it doesn't seem to be anything special.
It has a TV option, which (naturally) you need a TV tuner for. It also plays your music and lets you watch DVD's, etc. Oh, and it views photos too.
All in all, just another lousy way of trying to "entertain" your basic user. I daresay it's not too popular.
