Why do I need to download a separate iOS 9 build for each device?
It feels crazy because each build is >2GB and I got several devices.. its kind of fuxx up!

Each build is designed for the hardware that it runs on (iPhone 6, iPad) and contains the drivers for each hardware version.
When you get the first build on, OTA upgrades should be smaller then the IPSW files you download from the Developer website.
