I already use Ubuntu + Miro on my media center as my primary tv experience, so it's cool to hear about a tv-centric Ubuntu distribution that actually runs right on the tv.

Some of the cooler features include:

• Easy integration of broadcast, online services and applications
• Shared-screen experience with iOS, Android and Ubuntu devices
• Pause on one device, resume on another
• Ubuntu One integration
• App framework
