alt Hacker NewsTen- or fifteen-year-old hardware is still perfectly serviceable now for some modern applications. (The decade-long Intel monopoly drought of 5% generational improvements to CPU performance has a great deal to do with that.) So this is not as strong of an argument as the same sentence would be if it were said ten years ago.
It's a plenty strong statement because all that hardware and more is included, back to years before the drought. 64 bit support goes all the way back to some Pentium 4s, including all the dual core models.
