I've been using the iPT as a test device but it won't work with iOS7, so I need a new device. I don't want payment, don't need phone service, so that gives me a choice: -New iPT -iPadMini Retina -iPadAir Given that I can test on the simulator for these, and not considering non-testing uses, what advantage is there to one over the other? I'm also considering a MBA/MBP for dev, so a iPad might be better as the MBA/MBP might not view the whole device on the screen (just a guess). The cost difference isn't much between iPodT/iPadMini There are more iPhones than iPads, but the simulator should work fine except speed (performance) testing, however, the iPadMini has the same processor so performance should be close enough. I can't see any problem with using an iPadMini Retina as my ONLY test device, it has the resolution, size factor between the Mini/Air is automatically handled by the OS. I don't want to buy more than one test device.
