Whilst the way Amazon has been doing business is very distasteful (and I was on Apple's side in the recent DOJ trial), I can't see a problem with this offer and in fact am very pleased that a company has finally offered it. The majority of consumers are unlikely to purchase both an ebook and physical copy of the same material, so offering a slight increase in price for both seems like a win for everyone.
