Took a taxi back from Tim O'Reilly's talk last night, amazed to find a TV built into the cab. After the novelty wore off, and the 5 minute long advert had finished I started getting a little annoyed with it. I was able to turn off the sound but not the picture, which is almost impossible not to watch. I hope this is not going to become the norm, spoiling what is normally a relaxing indulgence.
