The graphs of transfer rates are cool and all, but consider the average "mom" user - what are they going to do with that? Is a complete graph of transfer speed

The graphs of transfer rates are cool and all, but consider the average "mom" user - what are they going to do with that? Is a complete graph of transfer speed really necessary? It seems a bit of geekyness thrown in because it's "cool" rather than adding significant extra value over a simple text label with the current transfer speed.
