Nah, just a pathological complainer
Listen, I get it, it sucks that it's not more widely available. But in the real world resources are finite and choices need to be made. GW chose, for once, to be right there with a new format as it starting to take hold. They conciously chose the interactive ebook format, which can be conviently created and deployed but pre-existing software, in thus case iBooks.
Or would you rather they would have done absolutely nothing, or postponed something like this till they had designed, coded and marketed their own content delivery system?
