>>one of the cases PDF is being considered (and, based on Internet rumors, is already being used) is as an interchange format for CAD drawings? Now it suddenly starts mattering. If you have any component where getting a really accurate circle shape is vital (like pistons and their holes), suddenly all your components are slightly misshaped. Which would not be fun. Holy forking shirtballs - NO! The article rightly make a nice concise case against it. I'd add from my experience: perhaps PDF people think this would be a cool way to make more money, but only because they have not done any CAD/CAM/CNC work. Since I do CAD/CAM/CNC as a regular part of my work, and have spent time with PDF back to it's early days, that is a hard NOPE. But definitely a good nominee for the Bad Ideas Hall Of Fame, at least honorable mention. sheesh.
