Agreed with everything--especially the suggestion that Atom/ION is not 
the only way to get a power-efficient system!  (And using a Core 2 Duo 
or similar, you actually have a "real" CPU that's actually useful when 
you need it.)

Only thing I have to add is to make sure you get a power-efficient power 
supply (go 80 PLUS).
