There seem to be a few different Latitude E5580 :

At least the two first seem to have exactly the same specs but different prices. Why?

Under "for the home user" (translation from Swedish, http://www.dell.com/sv-se/shop/cty/sc/laptops?c=se&l=sv&s=dhs&~ck=mn) Latitude is not mentioned. Why?

Does not Dell have e-mail support for product questions? Why not in that case?
