Boston ad agency Hill Holliday asked five families to replace their cable connection with one of the current crop of networked TV devices: Roku, Boxee Box, Google TV, Apple TV and XBOX 360

The results show what many of us already knew: due to a mix of challenges ranging from intellectual property territorialism (e.g. Warner Bros and Netflix and other similar power plays) and the fact that, in most cases, the very cable companies you’re escaping are still providing the broadband pipe into your house, we’ve got a ways to go for truly “connected TV”.
