The goal, in terms of business model, seems pretty obvious - get/keep people to use Microsoft services and don't lose any more of the low end to Android. While Facebook and Opera Mini are built-in, so are Bing Search and MSN Weather. I wouldn't be surprised if they eventually add other services also. If they can sell this type of device at or near cost (which it seems like they are), and increase Bing marketshare at the expense of Android/Google, it's a win for them.
