Bummer for F1 fans — FanVision reportedly won't be back in 2013.
From a fans perspective, the only part I really found myself using during the race was the live sector times...and I think there's other apps for that, right? I couldn't bring myself to watch the video on the tiny screen when the real thing was right in front of me. Not to mention that COTA did a pretty damn good job of placing monitors around the track that had the F1 feed.
I can see how it might be more important to Will Buxton, but for me I had one hand dedicated to a camera and the other dedicated to a beer and/or Salt Lick sausage wrap at all times. One of those items had to get set down for the FanVision to be useful, which required a huge internal negotiation.
