One word "AirPower". They even had pictures of it on their site.
Yeah, but AirPower is a product they actually announced, put pictures of on their products, and even gave a rough date for its release, and then it didn't happen. That makes it vaporware. Unlike the 16" which has never been officially announced. But it is a bit weird to have this many rumors about it and still no sign of it coming out any time soon.
