Saying that Microsoft and Google can't deliver an 'integrated' product is far from the truth. Apple doesn't have anything on the iPhone that can't be described in a generic sense and then the work of functionality left to drivers. At that point it's up to the hardware manufacturers to do some good industrial design and make sure they don't skimp on hardware features.

You can provide and Apple-like experience on a generic device, so long as it has the requisite hardware functionality. This can be a different story when it comes to things like computers and laptops, but the iPhone 'package' itself doesn't have much but the touchscreen.
