Apple makes sure that before you ever use it that almost every single thing akin to what Dustin pointed out is a non-issue.
Google gives you an alpha/beta product and wants you to find the flaws for them, and maybe help shape it.
Using bread as an analogy, Apple gives you a beautiful tasty loaf ready to eat; Google gives you some dough and tells you to start kneading if you want some bread. With Apple you know you are getting a fantastic loaf and with Google you get to help bake.
Each has their benefits and drawbacks.
Apple is like one that makes the absolute best vanilla and chocolate ice creams you've ever had. And maybe in the back, they're working on an amazing mint-chocolate-chip, but they haven't quite found just the right supplier of peppermint extract, and until then, nobody gets to try it.
Google is like that crazy experimental ice cream shop that has all sorts of weird flavors available at any time, and sometimes they don't quite work out (like "pancakes") but sometimes they're huge successful breakthroughs (like "bourbon and cornflakes"), and they have no way of knowing which is going to be which until the public starts to taste them.
After all, the flip side is, "or announce that a flavor that you paid $600 for barely 14 months ago is end-of-life and will not be getting any updates".
The Google ice cream shop is actually a vending machine.
