32-bit CPU's can still handle 64-bit numbers, they just have to jump through hoops to do it (like, say processing everything on SSE or Altivec, or using really clunky libraries to do it "in software").
Also, the 64-bitness is of no use to Aperture (which processes everything in 128 bits on the GPU).
Finally, 64 bits isn't twice as close to "analogue" as 32 bits is (33 bits would be.) It holds 4,294,967,296 times as much detail (although with audio, 32-bit resolution is fine, it's the frequency that's usually the problem.)
