I am going to get a lot of use out of my 990,too, but I must admit I do not like it the way I like my F100....heck, even my N70.... I find it difficult to see with it. I use the view finder not the LCD except when I have to as in macro mode. The rest of the time I consider the LCD a battery eating nuisance. I *do* like " instant review", however and , of course, the ability to review all the pics on the memory card.
Still, I think Nikon is missing the boat not manufacturing an SLR to compete with the Canon D30 which is very popular around here.
Like you, it will be a a while before I part with $5000 or more for a product with a one year cycle life.
