iOS 7 is made to power just a handful of devices. If you want a new iOS phone, you have just two choices: the 3.5-inch iPhone 4S and the 4-inch iPhone 5. If you're in the market for a tablet running Apple's operating system, I hope you like the 9.7-inch iPad, the outdated iPad 2 or the 8-inch iPad Mini, because those are your only options.
If you're interested in an Android device, step right up, because there are thousands of them. You can get a phone that's as large as 6 inches or as small as 3 inches. You can find tablets that range in size from 5 inches to 13 inches. You can even buy an Android desktop, an Android laptop or a tiny Android Mini PC that turns any monitor into an Android media center.
