I was reluctant to move to digital. I had been shooting Velvia abd Provia 100F on my Nikon N80 and getting 20 megapixel scans on my Nikon 4000, so I would cringe at the thought of losing the resolution. Then one day I took my family up shooting at the Mt Baker ski area. I had just finished a roll and as we were driving down the mountain we took a turn to see a beautiful view of Mt Shuksan. My wife asked if I was stopping, but I did not want to load a new roll just for the one shot. That did it. It's better to have less resolution with the shot than no shot at all.
After having the D100 for two weeks I am very impressed. The camera shoots slightly underexposed (for defined reasons - see elsewhere), but I normally shoot RAW, so can deal with this easily enough. It shoots like my N80, with controls easily accessible. I shoot with white balance set to cloudy -1 and have had great color accuracy. I recently shot my neighbor's three year old's birthday party, indoors under fluorescent lights, in jpeg, with great results. A minor levels adjustment cleaned up the images beautifully with no curves required for color shifts. The flash does quite well as a fill flash.
Overall, I am quite happy with my D100. No, I am thrilled. I have no desire to return to film.
