When you go to an Apple store, guess what? They are going to support their product, show you how it works, and make sure you are happy with your purchase, or they will, in fact refund your money, letting you return the product. That's the model that is allowing Apple to win. They are not a "third party seller" like "The AT&T Store", or "Best Buy" (Worst Deal) or any of the other "vendors" of cell phones.
Product support is something that everyone wants. Being able to actually have it, is a rarity today, and Apple is demonstrating that if nothing else, that their customers are finding value in that.
The technology crowds that want "open" and "I can hack it" environments, favor Android, and promote them to their peers and go on and on about the "closed" ecosystem of Apple. There are specific features of Android (and WP7) that are dramatically different and more flexible that iOS. The ability to "change things" is where the line can be drawn in the sand between "supportable" and "not supportable" in many cases. Apple is conservative about what it wants to support, because it actually has support staff (count the number in an Apple store verses the AT&T or Best Buy, stores) which they are paying, and it is more cost effective to minimize what they have to "know" and "support".
Microsoft's success with Windows Phone-7 will first about market share, and then about growing a community. Apple started out with the ability to sell smart phones because theirs was the best, no competition, they could just sell. Android only made significant marketshare due to 2-for-1 or give-away marketing by Verizon before they had iPhone. Now MS/Nokia are dealing with a market which has users that have iOS/Android because they can afford a smart phone, and those that can't afford a smart phone at todays $200 for device + 2-year contract (or $600 without a contract) plus $50/month for data/features, or don't want one.
The Windows Phone-7 devices have to be demonstrably, a better deal. Everyone has either an investment in an unlocked phone, or a 2-year contract to ride out. That means that uptake of windows phone-7 will be prolonged by lots of factors, even if it was absolutely the best choice.
The developers will flock to the marketplace to be "the first XYZ app", so that part, will likely happen without "contracts/investments" being a factor.
But, until people really "like" Windows Phone-7, they won't be jumping in that direction.
I personally, value my use of AirPlay as a significant part of why i use Apple products. It's something that I want to have available to me. I have a backyard entertainment system that I can just turn on, and play my music through wirelessly without fuss. I like to walk into the house with my photos and videos on my iPhone, and switch on the TV and use the Apple TV to show my photos and videos to friends and family. At gatherings of friends and family we have "sharing" events through the Apple TV.
There are lots of reason people will keep their iOS devices and Android devices. User interface may not be the biggest "technology" reason why they are not moving to Windows Phone-7.
