21% of Windows users run 95, 98 or ME

IDC estimates that of the roughly 514 mln paid-for copies of Windows on desktops and laptops worldwide at the end of 2004, almost 21% were the aging Win 95, 98 and Millennium Edition releases. Among the 19 mln Mac OS desktop and laptop installations IDC surveyed, just about half were running releases predating Mac OS X.
