Win2000 Still Performs on 8-year-old Hardware
Daniel Iversen writes "Still 95% compatible with Windows XP, The Windows 2000 OS still runs very well on very old hardware - hardware with low specs it was never even meant to run on (tech setup guide - not a review). The broad question is, does the fact that you can remain compatible with today's applications and data on hardware that is almost a decade old, impede PC sales?"
95% = 19/(2*2*5)
2000 = 2*2*2*2*5*5*5
