	Actually the new strongarms can dynamically range their clock to
control power consumption. Running flat our they run at 600MHz and burn
450mW. They also have built in hardware support for PCMCIA, compact flash
and by extension IDE. To further that support they also have the SA11X1
companion chips, also very low power. Which give USB support, and
simplifies the CF+ and PCMCIA requirement as well. Top that off with the
fact that there are several low power chips that are mated to them for
video and audio applications already and you have quire a competitor on
your hands. I am still working through the Crusoe material but I have seen
nothing to lead me to believe that the StrongARM is just going to roll
over and play dead. Quite the contrary in fact.
