Perhaps companies should consider that technology and software platforms should not be about artificially constraining people and locking them into your walled garden of a cash till ? perhaps do something decent for technology users for once which is open and shareable between all platforms, after all apple has massively lifted from open source software projects for its own use without adding much back to the community ?, rather than just considering your own profits. The idea ibooks author has been programmed to only work with the aspect ratio of iOS devices ? how does it handle the taller aspect ratio of the iPhone 5s then let alone other devices. Your basically dooming users whose lives are already burdened enough – with unnecessary complexity, to have to use different software for different devices and platforms and layout everything out many many times in different software ? This is far worse than the situation need be ? but its not just apples fault either adobe are rubbish at the create once publish many idea as well, in fact this whole thing has stagnated for 6 years, from what I can see with nobody providing a decent solution to the ‘create once publish many’ platforms problem, apple your platform doesn’t live in a vacuum nor do your users wish to, it ain’t healthy. Why should I waste my time creating my content in your software if that means I’m locked into your platform with those files from then on ? its not in my interests thats for sure to only be able to sell my ebook on the iOS platform ?
