Given people like pointing out that consoles lose money on each sale, I wonder what the profit margin of an iOS device is over the average supported life time? Major Android vendors selling at similar prices to Apple, who don’t even have to pay for OS development seem unable to afford to provide support for 6 months, let alone The 5 years Apple supports a device. What is the margin after 5 years of support? Who is paying to provide that support, if not the companies that are benefiting from the platform, and that platform’s longterm support and consistency?
