As above, to upgrade the Dell XPS 15 - a single 4GB RAM stick, or a pair of 4GB sticks. Don't like paying Dell's rip-off upgrade prices at point of purchase, so before I go to an online retailer, anyone want to claw some cash back on a purchase?
I should add that I can offer 2GB sticks in part-trade if necessary.
