This reinforces the parent's point though, because now you have a fifth option with apparently different hardware on a different update schedule with different pricing. How much Linux incompatibility do you suffer from a regular XPS 13 versus a Developer Edition one?
To continue with the pit that is Dell BS, why is the "Developer Edition" of this stuck at 4GB of RAM when one of the other tablet-like versions had 8gb. My current machine has 64, my last ultrabook had 16gb, and my father's phone has 6gb (OnePlus 3t).
Why would a phone that costs half as much have an extra 2gb of RAM and twice as much storage? The phone has 128gb internal and we added a 128gb card.
