Me too!
AIM SmartyCam is probably the most full-featured, robust camera on the market. Nothing like pulling the video card and having the data already overlaid onto the video for quick coaching. It isn't cheap, but it's a damn good camera/data system.
And if they could automatically sync the video with the data in their analysis software they would catch up with "lesser" systems. I agree that the immediate overlay is a great feature (though not unique) and probably very high on your priority list as a coach, but for my purposes does not beat out integration with the data analysis software. That is quite possibly a reflection of my lesser experience and abilities to utilize them, but having to do everything for ourselves in a race weekend we need the quickest possible access to information that might help us adjust our driving and/or cars while also doing everything else required between sessions. We have found integrated video and data analysis to be an important feature at our current level.
