I've been doing a lot of research recently on the D700 and from everything I've read and heard is that it's a fantastic camera. It seems that it has all the right ingredients to produce stunning images. Additionally, it seems to be highly regarded for its ergonomics. Lucky you!
Ergonomics are great, picture quality has something special about even in RAW. The body is sturdy as a tank, feels a lot like a F4. Which already means I love it, back as 13 year old I was allowed to use my dad's back-up F4 to learn photography on film, slides and B&W. Another benefit is small files it creates, it makes post processing so much easier.
The one issue I see, so, is cropping. I am not talking about cutting some sides or going to portrait format, but rather cropping out e.g. birds. That's the only time the 12 MP hinder you. In a sense a D700 forces you to shoot better pictures.
Overall, if you can, get one. There are some from places like mpb.com with below 50k shutter count in very good condition for around / less than 400 Euro. You cannot do anything wrong.
Oh, a D700 doesn't do video. No problem for me, but if you want to do video that is a missing feature.
