I recently received my D700, MB-D10, En-el4a and 24-70 f2.8 lens. After attaching everything, I was looking through the viewfinder to adjust the viewfinder focus and noticed there was a spot near the lower right corner. At first glance I thought it was a spot of dirt. But after considering the camera was literally brand new, I thought maybe it was some excess "material," which was on the mirror or prism. Needless to say I was a bit disappointed. I emailed my problem to Nikon tech support and received a response that I should remove the lens and see if the spot is still there. I did, and in fact it was still there. Support give me two options, (1) return the camera to where I purchased it (which was on the east coast) or (2) ship it to Nikon's Service Center. Not satisfied with the response I called tech support for live feedback. The tech agreed with me that whatever the material on the viewfinder was, it was probably on the prism or the mirror and would not have any impact on the images I take. This naturally, was after taking the lens off. Does anyone have a different point of view on this?
If this "spot" doesn't affect anything then I will probably just ignore it rather than go through the hassle of returning it or shipping it back to Nikon's Service Center.

Seriously, take a picture of a light, even surface (white or gray card should do), put in into your editing program, play with it, especially expsure and contrast-wise, and see if it shows up. If it doesn't, no problem; if it does, back it goes.
f/8 and be there?....but I'm moving as fast as I can!

I feel for you. I know how it feels unable to sleep because the spot keeps bothering you (even if it doesn't affect the picture at all). It's there every time you look at the viewfinder, and you will always notice it.
I had the same case with my D300 after taking it out on a dusty/rainy trip. I tried to clean the sensor (wiped/brushed/blowed) but the spot is still there. Until it occured to me to actually clean the mirror (and the area right in front of the mirror) and it actually did the trick. You might want to do the same but BE VERY CAREFUL (i.e. use special sensor-cleaner tools).
One thing for sure, you won't be able to "just ignore it"..

Welcome to Nikonians!
It is certainly true that, if you can see the spot in the viewfinder, it will not appear in your images. The mark is probably on the mirror or (more likely) the focusing screen below the pentaprism. If it disturbs you, it may well be possible to dislodge it with an air blower like the "Rocket"

Since in an SLR none of the viewing system, other than the lens, is part of the final imaging system the simple test of seeing if the spot remains when the lens is removed is a 100% accurate test of whether the spot will show on pictures or not. _Any_ spot that remains when the lens is removed will only affect viewfinding functions (e.g. annoy the user, block visibility of some VF display, ...).
If the spot is crisp and sharp it is 100% certain that it is on or above the frosted surface of the focusing screen and on or below the bottom surface of the prism. A flaw on one of the reflective surfaces of the prism would be out of focus when your eye is focused on the screen image. Any dust or flaw on the mirror would also be very diffuse in the VF because of its distance from the focusing screen. You would not likely see it as a spot. On a film/FX body a spot on the mirror at the very top near the hinge can be close enough to the screen to yield a decernable spot near the bottom of the VF image, but even then it won't look sharp.

Welcome to Nikonians and SLR photography. As noted above most of the viewfinder system is seperate from the film/sensor in the SLR camera. So what one sees in the viewfinder might not be what is recorded. The view finder has many flat surfaces that are not verticle and can hold many foreigh objects that become visible in the viewfinder. One can remove the lens and see if there is anything on the mirror and then tilt the camera back and see if there is anything on the focusing screen. A good puff or 2 of air from a quality blower should remove any foreign objects. Be sure to follow the instructions in the manual. Do not insert the blower tip into the camera body and have the front of the camera pointing down so and particles disloged will fall down and out of the camera.
Out of practice, I try to clean all new cameras, lenses and focusing screens before using them. The body and lens caps are not real tight fits so there is a chance that foreign matter can get on their surfaces. I also try store my cameras with a lens on because of the better fit and in a clean camera bag.

Returning it? Yikes! Don't do that over a bit of dust or hair or environmental whatever. Changing lenses from time to time allows all manner of dirty bits to enter the camera chamber and the first two items encountered inside the camera are the mirror and the bottom of the viewfinder prism.
Anything normally visible to the eye looks several times as large when seen through the viewfinder. It's a visual distraction and there likely isn't a photographer anywhere on earth who hasn't been annoyed by these bits. It's impossible for any dust on the mirror or prism to affect a photo (except for composition mistakes made by the photograhper who's distracted by the dust bits visible in the viewfinder).
I think Brian mentioned elsewhere in this thread that a few blasts from a Rocket Blower should blow dust and hair out of the way. Just avoid the use of a compressed air can because it blows air with too much force. A rubber squeeze bulb blower like the Rocket Blower is perfect. From time to time I encounter a piece of dust or a hair which just won't dislodge though and have to resort to a lens brush to drag out the offending bit.
