Keep in mind that 6-10mbps isn't going to be enough for casual users in a few years. Take gaming for example. Companies are regularly releasing 6-10 GB patches willy nilly because they assume their customers can download them in a matter of minutes/hours.

And that's now, when there's still large urban areas in a lot of countries on DSL. Once that DSL is phased out, rural areas are going to need better sattelite options or expensive long stretches of fibre to not fall behind the curve.
