I just wonder a bit about the Google Zeitgeist . In March Mac OS had 4% and Other had 3%, but since April Mac OS has 3% and Other has 5%. What is this Other category? OS/2? FreeBSD? HP-UX? It seems strange that these should make up 5%. Maybe it includes searches made through google's WebServices, in which case I wonder if Safari's built in search field uses WebServices?
