Ian Lamont writes "A Microsoft-sponsored report that describes a hidden "Apple tax" has fallen flat among the technology press. Roger Kay's report (PDF) compares various PC and Mac configurations, and claims an all-Apple household's costs would add up to an extra $3,367 over five years. Tech columnists and bloggers have slammed the comparisons and claims made in the report — even Mac-baiter John C. Dvorak calls it propaganda. However, some Mac fans still see a pro-Microsoft press conspiracy. Even if the comparisons are questionable, Kay's report and the accompanying television ads have clearly struck a nerve among the Mac faithful." Meanwhile, Linux users everywhere are scratching their heads.
