"For the third straight survey, over half of the respondents (65.91%)
use some flavor of Windows (3.1, 95, or NT) as their primary
computing platform. (Most notably, the percentage of those using Win95
has increased from 28.5% in the Fifth to 42.9% in the Sixth.) This
percentage is up strongly from the Fifth Survey (58.6%) as well as the
Third Survey (61.5%). The remaining users are mainly Apple users
(25.85%). The strong presence of Apple users is most likely a result of
heavy use of the Internet within educational setting, an area where
Apple has traditionally strong marketshare. The other operating systems
of the world (UNIX, VMS, etc.) are used by less than 5% of the
respondents each. In GVU's First WWW User Survey, conducted January of
1994, over 90% of the users reported UNIX as their primary computing
platform!"
