Flashing highlight warning vs histogram S2 vs D100

I come from a PJ background and am sticking my nose under the wedding photography tent. While assisting a local shooter I see that his Canon has a feature whereas the LCD shows what areas of the shot are blown out by flashing it, much like a Photoshop Gamut warning.
I've been leaning toward the Fuji S2 or D100 (closer to the S2 so far). I see the Nikon D100 has this feature wheras the Fuji S2 does not.
Does anyone, especially wedding shooters, miss this feature on the S2? Or does the histogram cover this just as well?

Thanks for the help.
