Well, the PC goes at least to 10 nanosecond resolution, even now. There
are plenty of 100 Mhz '486s out there, so whole nanoseconds is not such
a reach or so far in the future as to be neglectable.  Probably a lot of
applications could use profiling to that resolution even today.

Also, I suspect an awful lot of those TI DSP chips are going _into_
PCs, that being by far the largest installed base to target, so the
Gigahum in in the box, if not on the motherboard (where 60 nanoseconds
seems still to be the state of the art).
