Greg's probably right on this.  The x86 architecture keeps improving in
both performance and efficiency.  I'm looking forward to being able to
use a 586 in the JUMPtec form factor, which is mind-bogglingly tiny for
a PC clone.

The AMD Elan SC400, JUMPtec's CPU, is a 100 MHz 486, though to get
the last 34 MHz of that requires a heat sink.  The DIMM PC module
including the two serial ports, parallel port, and floppy controller
draws 400 milliamps from its single 5v supply at full bore and 160
milliamps when idling.  That should be enough to make a comparison with
the P166.  (We don't have the latter, the one Cell PC machine we have
is the P233, which needs no heat sink even at 233 MHz!  In contrast
we have 10 Jumptec's at this point, and 10 VGA/ethernet modules to go
with them.  Incidentally the 340MB IBM Microdrive works with these,
even runs Win95, it's a really tiny package!  Will put something on
http://wearables.stanford.edu about this in a few days.)
