He has also served on the editorial staffs of ZDNet, PC/Computing, FamilyPC, InformationWeek/TechWeb, and Windows Magazine.

Finnie has considerable experience covering operating systems both journalistically and in detailed hands-on evaluations. For many years he focused on Microsoft's Windows operating system. He wrote a book on Windows 95 (The Underground Guide to Windows 95, Addison-Wesley, 1996). In September 2006, he embarked on a three-month test of Apple's Macintosh with OS X and surprised himself by not switching back to Microsoft's operating system.

Scot’s Newsletter is Finnie's personal blog and notification newsletter. The newsletter was discontinued in May of 2010. The blog is functional, but hasn't been updated since September 2009. When it was updated regularly, Finnie covered operating systems (primarily Windows and Macintosh), security, home networking, the Internet, computer issues, and technology at large. Automobiles, alternative energy sources, and alternative automotive technologies are some of his other interests.

These days, most of Finnie's writing can be found in his Computerworld column (monthly), his Computerworld blog, and at his Twitter account, @ScotFinnie.
