The problem with this beautiful theory is that lots of new users of XP can’t or won’t “Research and learn” or “configure” their machine properly.

and lots of current Network/RPC/LSASS/…-worms only run or are targeted at NT-based systems:
like all those cute unpatched XP-Home machines which are being used under admin-account
→ why do you think the average time-to-infection on an unpatched/unsecured PC with inet-access is about 20 minutes… ?
