CWmike writes "Gregg Keizer sifted through many threads of e-mails released under the 'Vista Capable' lawsuit to dig up this jewel...More than a year before Windows Vista's release — and long before Apple started poking fun at the OS — Microsoft officials were already worried about comparisons between Mac OS X and Vista. An e-mail thread from October 2005 showed that an article in the Wall Street Journal by Walt Mossberg grabbed the attention of managers at Microsoft. In a column headlined What PC to Buy If You Are Planning On a Vista Upgrade, Mossberg alarmed one Windows manager who forwarded a bit from the column.... 'You won't have to worry about Vista if you buy one of Apple Computer's Macintosh computers, which don't run Windows,' Mossberg had written. 'Every mainstream consumer doing typical tasks should consider the Mac. Its operating system, called Tiger, is better and more secure than Windows XP, and already contains most of the key features promised for Vista.' Warrier added a comment of his own: 'A premium experience as defined by Walt = Apple. This is why we need to address [the column].'"
