Thus catching at least some % of defective Airs that might otherwise have been sent out? The idea of an Air being non-returnable if ordered with preinstalled software (iWork. Office for Mac) originally struck me as a disadvantage... in case enough's wrong with the unit that I need it to be swapped for another one, in order to avoid embarking on an uncertain voyage or one or more repairs. But on further thought, if somebody has to do the work of putting into it some customer-selected combination of optional softwares... well, maybe that could be advantageous too? Almost like another (partial) inspection? For example... if the screen looks bad, maybe they won't send that one out? What do the more experienced Air buyers among us think?
