Abigail's point is that 64-bits needn't cost that much and isn't
big iron. So Abigail points to a low-cost 64-bit piece of hardware with pathetic specs. No joke. It is a 64-bit CPU and isn't big iron. 64-bit has to do with how the CPU works and not anything else.
An even better example is the Nintendo-64. The 64 in this piece of outmoded hardware is the fact that it is a 64-bit computer. It isn't big iron, it is cheaper than the Sun, and they don't even sell computers that pathetic any more. Also your playstation is a 128-bit computer, and many video cards are 256-bit. Yet neither qualifies as super-big iron. Video happens to a problem where wider words are good.
