The Oxford Dictionary of Computing has revealed a little known fact about Apple's Macintosh computers.

According to the entry under Apple, as well as running Apple's own software, the computers can run Microsoft Windows.

While it is true that a Mac can emulate Windows, with a little help from Microsoft's Virtual PC, the news that Macs run Windows is likely to surprise even the developers at Apple.

The flaw is all the more concerning since the dictionary is compiled by a team of, so called, computer specialists. "Making it the most authoritative and up-to-date dictionary of computing available," according to the blurb on the back cover. It costs £9.99.

The entry credits Apple for pioneering the desktop and windows metaphors for the user interface, and it describes Apple as "an early market leader in the field".
