Some of the statistics that you are seeking would be available from those of
us running web pages and using such services as "Pagecount" to serve as a
visitor counter. Pagecount tracks the operating system as well as the
browser (if known) and provides the totals for the user. It would not
answer all of your questions but might provide a useful beginning. For
example, over the past month since I began a revised set of pages for our
museum the stats are as follows:
The Operating Systems of Visitors
Win 95 732
Win NT 74
Win 3.X 50
Mac 57
Linux 3
SunOS 13
Unix 3
Other 160
Web Browser used by Visitors
Netscape 1 0
Netscape 2 31
Netscape 3 193
Netscape 4 303
Explorer 562
Mosaic 0
Other 3
proxy and Cache servers
proxy servers 3
Cache servers 11
Direct 1078
I can supply longer term statistics of the same kind if desired but I have
found the ratios to be about the same.
