Are you aware that while ora charges $49.95 for eBook versions of Mac OS X and iOS internals, amazon only charges $28 for the kindle version?!?! A bit if a disparity to say the least!

Sorry for my delay in getting back to you. Mac OS X and iOS Internals is published by Wiley and we're pricing at the publisher established ebook list price. We do have sales that include Wiley books, and you can also take advantage of the Buy 2 get the 3rd free discount which is OPC10. More information on this can be found here: http://shop.oreilly.com/category/cust....
When you purchase these ebooks from O'Reilly they are DRM-free. This means you will have access to multiple formats (PDF, ePub, and mobi) while purchasing from Amazon you get one format. You also get free updates as they become available. Thanks for writing and have a great day!
