I think when discussing Apple's attention to detail it's important to point out that the current iPhones are extremely polished. But remember that it wasn't very long ago that you couldn't cut and paste on an iPhone.
(BTW. I do think the iPhone is more polished that any current release of Android. I'm not sure it matters though. Windows XP is laughably less polished than OSX, but it doesn't seem to be hurting in market share.)
The reason you couldn't cut and paste was that Apple doesn't release a feature until they polished it. They didn't let you make apps until they'd made the App Store, and there was a year of complaining, but when they finally did it they nailed it. Ditto cut and paste, which now works better on the iPhone than it does on anything else.
