Yes, if you look at the pictures (and description) here: http://www.medgestore.com/products/kindle2-latitude.psp
you can see that the latitude has a front pocket where you could store the eLuminator.
Lucky! I have a different m-edge case with the eLuminator light, and while the light is really great (I love that it has three different intensities), my case can't carry it safely so I end up putting my Touch in its case, the eLuminator in it's slide-in-slot, and then the whole thing into an envelope to carry it around! Annoying.
