Media center software running on top of media center software seems silly (cue meme), but maybe you really love Plex's UI that much. Or maybe you love the Google TV hardware, but not the software? Either way, you now have options.
Plex's app is now optimized and available for Google TV, promising access to all the web-based content provided by services such as Vimeo and CNN, along with the local files you supply. And while this app will be 100% redundant down the road, it's a good way to access some services which don't yet have apps on Google TV. [Android Marketplace via Plex via Slashgear]
