The figures I've been able to dig up for market share for my presentation next week (a mix of Gartner, MS and Oracle sources) suggest that Windows accounted for about 35% of Oracle RDBMS License revenue in 2007. (and had likely close to 40% of the windows rdbms market overall). If anyone has stumped up the $3500 that the IDC review costs ( http://www.idc.com/research/view_lot.jsp?containerId=224350) I'd love to see a couple of those tables :), so by sales volume Windows is, or at least has been, significant, but likely not the most popular. By installation count it may well be. My guess is that Oracle's share of the windows database market has slid somewhat since the release of SQL 2008 though.
