A difficult question. I've been thinking of the D1 since it was announced nearly a year ago. Two weeks ago, I was able to borrow one for a weekend. I used it with an N80 and Proneia 6i and my 80~400 VR lens to take "similar" images at our local zoo. The 35mm (AGFAchrome) and APS films were scanned to PhotoCD. I used the BASE*4 (1536x1024) resolution images to compare with the D1's 2000x1312. I "cut and pasted" and then printed onto A3 size on my Epson 1270 printer. The 2 "film" images were clearly superior to the D1's and PhotoCD has 1 "higher" resolution file (3072x2048).
My conclusion is that the D1 will not come close to replacing film for my needs.
However, for "editorial/photojournalism" applications, it's fantastic. Image access time is digital photography's strength. The ability to have B&W or color from the same image is "a piece of cake". A 64MB card is around 40 exposures. If you only take 12 pictures, they can be downloaded and erased from the card.
The Kodak scanner is "darn good". In fact, I was almost ready to part with $1400 for one when Nikon announced their 4000 and 8000 models. I'm very interested in trying the 8000 since it can also scan 120 size film.
