PCs and Macs?

IUBio archive at http://iubio.bio.indiana.edu/ is
a repository for biology software, search site for
GenBank and related sequence data, and archive of
bionet news (like this group).

IUBio archive's HTTP server logs information on browser
kind, including computing platform.  From the last 18 days
of logs I've pulled the following statistics of
computing platform representation.  Note there seem to
be two broad subcategories -- callers for bionet news which
are likely from the general public (or a subset of them),
and callers interested specifically in biological science
software and data.  

The bionet archive news calls mostly originate from general web searches 
(altavista, aol, excite, etc.) that are searches on topics related to the 
general public's ever present interest in sex, health, cooking and 
the like.

The other calls are for biology software, GenBank and related
biology data.  They generally don't originate from the
common web search sites.

Total HTTP server calls:   33983

   Macintosh browser :  5095  -- 25% of biology 
   XWindow browser   :  1679  --  8% of biology 
   remainder         :  3760  -- 18% 
   
This is a quick and dirty look at platform usage. 
Better sources of Internet usage by platform are available
elsewhere.  The remainder category includes robots
and software agents that don't identify a platform.
