ZigBee and Blutooth cannot be compared. They are too different 
and serve totally different purposes. As for size and cost look 
again. We are producing a module, based on a single chip solution 
that is far smaller than any blutooth solution out there. 
Currently the unit costs are around $1.50 but we expect it to go 
below $1 soon. And as for power consumption, ZigBee offers a near 
total shutdown in sleep mode. End nodes need to wakeup only when 
they have to, for example when a switchs closes or opens. Our 
open/close sensor units for example, are designed to last well 
over a year on a 3.6 volt button cell. Obviously  their real life 
span depends on the number of open/close actions.
