On the simple page showing prices, Nat Tuck compares laptops that are not equivalent. The Ubuntu laptop's default graphics card is an integrated graphics card with no dedicated memory. The nVidia 256MB video card Dell added as an option for the Ubuntu laptop is a better comparison and results in the exact same price for both systems. (Note that Nat reports a $79 savings for the Ubuntu laptop and upgrading to the nVidia video card costs $79.)
