Apple's CEO says that Android is fragmented and that the open vs. closed dilemma is not important as long as Apple's proprietary mobile operating system manages to provide a better user experience.
My point on this: Steve Jobs may be right; i.e., the iOS ecosystem is certainly less fragmented and more homogeneous. I have an iPod and I do appreciate it. That's right.
But what he forgot to tell you, is the price you pay for this self-consistance: namely, the reduced possibility of choice. You have a lot of different choices for Android, from budget to high priced devices (for me, I'm quite fine with a rather inexpensive HTC WildFire).
Conversely, not too many choices are left to you, if you want an iOS device: an iPhone. What else?
