Very worried. It may well be true, as Paula details today, that desktop Linux is going nowhere fast in the U.S. Microsoft’s willingness to let users back-off upgrades and stick with XP may have stopped the potential rot in its market share. But it is taking enormous effort for Microsoft to hold its server market share against Linux’ inroads in the enterprise. Another important point. The U.S. is not the world, and Microsoft sells more than just Windows.
