EDIT: A lot of folks seem to be interpreting my comment as implying there is no value in this technology. That is absolutely not the case. There is huge value in widely deployed screening like this (especially since it looks like the specificity is quite high). My point is that these devices will not be replacing diagnostic equipment (in fact, it may very well increase its use as more conditions that would otherwise have gone undetected will now be flagged for further diagnostic testing).
