Here's an example I've recreated... I'm downloading (again) some offline maps, and it's pretty clear that that in reality you might not get many of those 1000Mbps that GF is capable of. This show ~31Mbps for a real-life download - nowhere close to using the Gig. And I'm not confusing bits and bytes! It's not that it's GF's fault, it's just most of the sites (Microsoft in this case) around the Interwebz just aren't offering those kinds of speeds.
And then there's the lag-ass remote control, no PiP, and not "real" phone offering!!
