Marketing and creating perception for demand, that’s all it seems to be right now.I'm not real sure the whole point of the configuration process. Other than if you configured a Launch Edition, you can eventually order one (but can change to another configuration later).
If you did not configure a LE, you can't now switch to one. That may change if people bail on the LE that configured one "just in case".
Zero commitment to anything as far as we have been told (except maybe choosing between the R1T and R1S)
And I’m a believer.
