Those chips are hopelessly underpowered for any real work.

If you restrict yourself to PC-104, this is true.  However, StrongARM is the
best power/price/performance option.  If you're willing to do some
customizations beyond stacking PC-104 cards, then go StrongARM.

BTW, Intel is actively developing StrongARM.  They've got an entire design
team down in Arizona working on it.  Unfortunately, I think they are going
to bumble with StrongARM because they are uncomfortable with it's price and
performance competing with the desktop.  "Intel, change happens.  Either
make the change, or lose fighting it."  IMHO.
