Full stack means better integration between hardware and software and hence a better final product. Apple has been showing us this for years. Their product set has always felt very polished and cohesive. Plus, technology and programming languages have become very cross-stack friendly. For example: if you know JS you can (with some work) program a server in Node, your Db with Mongo, and client side with straight JS. Yes, there are some complexities but the basics are all the same. Furthermore, development costs for this are way lower than legacy systems that have never heard of aajax or a MVC.
