I own 2 N90s's and I think they are awesome. One has a data back, and both have the MB10 battery adapter. But I see so many raves about the F100 that I am wondering what I am missing. I am also drawn to possibly spending money that I don't have to buy an F100, even though I have more 35mm Nikons than fingers on my hands. As far as I can tell, looking at the specs, the F100 as a matter of fact and logic doesn't have much that the F90s doesn't, at least that I would use -- except for multiple autofocus sensors. So I would love to hear from those of you who own both models, to give me your two cents' worth as to what I am missing, if anything.
