There are HP laptops with user-replaceable RAM, such as the Pro and Elite Books. The 13" ones are comparable to the XPS line in terms of size / weight / performance. I don't have experience with the other sizes. The top panel being metal is also nicer in my opinion than the weird sticky thing on the XPS. The company I work for uses those, and they don't seem to have any issues with them.
