Just looking at the dell website, it looks like the xps 13 developer edition still needs to be updated. The updated 13&quot; xps has the 6th generation intel and better pricing. It could be they just have not updated their website, which is not surprising to me from Dell.
There is also the possibility Adorama is getting a deal from Dell to sell their laptops for less than dell.com. Maybe they have un-bundled some services, or added some bloat-ware.
