I just discovered however that for the Dimension E520 vs E520N, if you select "No Monitor" in the options, the price difference jumps from $80 to $140. For such inexpensive systems, that represents just over a 25% savings by selecting Ubuntu instead of Windows ($549 vs $409). At that kind of discount, would you consider Ubuntu for yourself or others (e.g. relatives) even if you hadn't before? Can Microsoft effectively compete in the low-end market?"
