64bit OS market share - I wonder what percentage of Windows and maybe other OS running computers today are running 64bit OS?
Well I don't know an exact number, but I know Microsoft has stated that they expect the number to go over 50% on Windows 7 release. Which means it's less then 50% now.
For a ideal, from the steam hardware survey Windows XP 32 bit (-2.98%) 62.41% Windows Vista 32 bit (+2.02%) 26.49% Windows Vista 64 bit (+0.73%) 9.52% Windows 2003 64 bit (+0.15%) 0.91% Windows XP 64 bit (+0.09%) 0.34% Windows 2000 (-0.07%) 0.19% Other (+0.04%) 0.13%
