First, Windows isn't going away, if for no other reason, because the lion's share of businesses are locked into Office. So x86 isn't going away. Thus Intel is not dead-meat-waiting-to-happen. Wintel will eventually have a huge advantage in the tablet market (as well as desktop/laptop market) because of Office.

Second, if Intel didn't have something good coming for smartphones, would Nokia have tied itself so closely to Intel with Meego? I don't think so.
