No, your reading comprehension is just failing you.
I said Apple has superior integration across their product lines than other platforms. That's why I said people with other Apple products (iMac, MacBook, iPhone, iTouch, AppleTV, etc.) tend to buy other iOS devices.
Look, it's pretty simple:
Windows Mobile couldn't even access Zune services, and had literally no XBL support. Microsoft service integration on Windows Mobile was bare at best, and there wasn't really much in Windows on the Desktop. All it had was a Sync Client, which iTunes also provides for iOS devices (including synching Outlook Data). I wouldn't say it was any better integrated with Windows than the average iDevice back then (and certainly isn't now), but iDevices are clearly superior to competing products when it comes to integrating with Macs and other Apple devices and the software on their computers.
What I wrote was pretty clear... Apple's devices have better integration than other manufacturer's devices. That's a driving force for people to invest further into their ecosystem than competing manufacturers who only loosely integrate their products.
Microsoft knows this. That is why they're tying Windows Live into everything (starting with XB360, then their mobile platform with Windows desktop/tablet to follow).
