With all the RVs and vans out there on the road, why hasn't Roku come out with a 12 volt TV. We are twiddling our thumbs waiting.
Roku only just started making their own TV's. Most Roku TV's are made by 3rd parties and license the Roku software. 12V TV's are a very small market. That said, some small TV's may run off of external power supplies and could possibly be used with some form of 12V cable. Not sure if any run Roku OS, though.
