I personally think Apple is killing themselves by not letting any other manufacturers make a phone using their OS. They're making a monopoly on their own item, which isn't even all that great to begin with. If they let things be a little more flexible in operation and let some other people develop phones using their OS, they'd probably be more dominant in the market. As it is right now, yeah, they're not doing bad.. but think about all the competition it would stir up for Android? Part of Android's success is the freedom to do almost anything without needing to root/jailbreak your phone. There are some added benefits to rooting an Android phone, but jailbreaking an iPhone is practically required to get your money's worth. It's a major deterrent for me, personally. After owning an Android phone now for going on 2 years, and my plan being up just in time for the iPhone 5 release, I'm honestly not sure what I'm going to do. Unless iOS 5 or whatever it's called pulls some major functionality out of its ass, I'm probably sticking to Android :/.
Not to mention I HATE companies that release a product, then a few months later dangle an all new, even better one in your face. Sure with Android having so many different suppliers and stuff the same thing happens, but at least Android (for the most part) shares the same functionality across the board (OTA updates usually allow even my old Motorola DROID to do pretty much everything the newer Android phones can do)
