Also, didn't see any information in the news item on how you actually purchase this.

Personally, I would prefer to see a Pooley's type of deal, where one can download the whole guide (using, say, Goodreader) and have it permanently available for browsing and one could synch regularly. Just because one sets out from A to B with alternate C doesn't mean you're not going to want info on D and E, especially if decisions are being made when airborne.
