A couple of other things to consider from a fresh perspective - I made the change to a D1 from a F100 about 6 weeks ago.
Some benefits of digital: Digital lets you shoot more photos and select your best. If I want a shot I'll shoot a sequence of 6 or so. With film I didn't do this unless it was back when I got paid to shoot and film cost was insignificant.
Digital is like having a darkroom. You can change exposure a couple of stops each way, tweak color balance, dodge & burn with some limitations.
Digital lets you caputre images in lower light, and lets you change film speed for any situation. See attached photo shot with D1 70-210mm 4-5.6 at 800ISO 1/250 f8.
Some barriers to digital: Digital does require more active color management to get great images where with Velvia I got it straight out of the camera. If I was rich and cost wasn't an issue I'd stick with film and have my images custom printed.
Your camera may be heavier. You will loose wide angle - that is an issue for me since I like to use my 35-70mm 2.8 primarily. But you gain on the tele end.
