So, I have not used a D1. But everyone who has told me this. The only redeeming value to the D1 when it came out was that it was really the ONLY DSLR (Nikon) out there. It is built like a tank, and has lots of customizable features, but in the end the technology was so new, it just wasn't all that. It was kinda what people used by default.
So, as cameras have come out, the image processors have become much more refined, and suited to normal every day amateur use. A D70, D50 or D40 would provide a much higher quality IMAGE than the D1. It may not be built like a Panzer, have the cool bottom grip, or have a 1/16000 shutter speed, but the image quality (which is what really matters in the end) is better.
Saying that, you've already bought the thing so go have fun! You may find out its perfect for you. Just because 95% of people out there would do something the opposite way you do, doesn't mean that they are right or you are wrong. Plus, people will come up to you and give you lots of attention, and maybe some hot chicks will ask to model for you (wishful thinking).
Edited to add: Oh, you didn't buy it yet. Nevermind the last paragraph. Also, I'm going to guess that having RGB on your camera is close to a must. I've never used a camera that didn't use it, but color reproduction is SO IMPORTANT. I'd hate to see this camera frustrate you by leaving you wanting more image-wise. It may even affect your ability to sharpen or increase saturation. I don't know, but these are things you need to ask someone about first.
