Apple gets my vote. The problem with Mac zealots is that they're usually too stupid to even consider another point of view.
<p>Even Linux zealots are usually intelligent enough to admit that at least there are <i>some</i> good things about the various Windows OSes. AMD and Intel zealots are usually just interested in performance, and will switch with the tide. MS zealots are usually intelligent enough to recognize the good aspects of their competition too. <p>So, again, Apple gets my vote for the most virulent and insidious fanboys.
