Matt Richman on his blog:
It all comes down to this: Apple can manufacture products that are the nicest and the fastest, sell them in stores its competitors don’t have anything truly comparable to, and at prices its competitors can’t match.
This will bifurcate mobile technology.
Apple customers will get the best of everything. Apple’s hardware and software will be the best, and they’ll be designed for one another. App developers, accessory makers, and other third parties want Apple’s customers to be their customers, so they’ll design for iOS first.
If you’re not an Apple user, you’ll be a second-class citizen. You’ll get a lesser user experience, and third parties will consider you a secondary priority.
