forget Linux enthusiasts. Whole countries, like Russia or China, have national security interest in it - beside everything else, Intel chips has VNC server built-in on the silicon :). China has been making great progress in building its national computing platform, though not sure whether it has reached the desktops of their government employees. Wrt. Russia - it again lifted the ban on buying foreign hardware for security services, time to upgrade has come again i guess :) I mean, even such guaranteed markets and money available is still not enough to even come close to Intel.
