Im talking Cosmetic's! Between Standard, BOS Upgrade or The Ralphie Model which I thought was just plain cute. Personally I thought it was freaking awesome to have Ralphie Model. Made ED-E look more like a Pet than a floating scrap heap.

If by Ralphie Model you mean the Divide model, I like that one better, as he seemed more like a companion and not some autonomous subroutine.
