Thank you guys for responding with some very sound advice. Let me assure you, and Jonny apple, especially, I LOVE my D90! Even though I was "wanting" the new D700, I am very glad that I bought the D90 when I did. I have had great fun learning to use the camera and taking so much better photos than I did before. Now if I could just get around to making a website with my photos, I would show some to you.
I STILL want the new/revised/upgraded D700, whatever it is called, and I still plan to buy it. BUT, I am NOT going to get rid of my D90. It is just too nice.
Of course, I have added a couple of lens....
Tamron 70-300mm (the real cheap one, but it works good enough for me)
Nikon 50mm 1.8
Nikon 18-200mm VRII
and this morning....
a Sigma Bigma (used for $620) 50-500mm with Tiffen filter.
shushhh..... don't tell my wife.
