So, Google TV, Apple TV, Roku, Boxee, and now Ubuntu TV. I think there's going to be problems making it a standard install because there's no standard setup on TVs. A big hamstring is the lack of Blu-Ray support in Linux (true last time I checked, maybe not now) but I can easily see a point soon where that doesn't matter anymore.
So, the set-top is the new desktop? And is this reason to go to Linux Mint or even straight Debian on machines you want to run at work?
