This sounds like they are going to deliver a truck that everyone is going to want/need to upgrade at least something, and are depending on this post-production upsell to keep things going. Reminds me of the Apple tax of only bare minimum RAM and you can pay a premium to upgrade it to something usable. And for Slate this fits well with the “customer can service/upgrade everything outside of battery stuff” as this lowers their overhead, and then are making a deal with a chain to do the servicing as the only alternative (and depending on which chain that is, and if the one near you is run well, could make this wildly different experience).
