When reading the comparison of the D100 vs. the D70 on e.g. dpreview.com I see that they mention that the D70 has a x.75 magnification and an 18mm eyepoint whereas the D100 has 24mm eyepoint. What does this mean exactly?
When looking in the viewfinder of the D100 I see a kind'of small picture far away (well, not really - but you get my drift). Is what I see through the D70's viewfinder going to look even smaller and further away?
I remeber once I compared one of my old Nikon SLRs to my friend's Olympus SLR and noticed how the picture in the viewfinder looked much closer and larger on his camera. Needless to say I liked the Olympus viewfinder a lot!
I am seriously interrested in buying the D70, but if the viewfinder is even worse (smaller looking) than the D100's, I may want to reconsider...

The eyepoint distance is the distance your eye can be from the viewfinder and still see the entire image. Generally speaking, a higher eyepoint (greater distance) means the image is smaller. High eyepoint viewfinders are very attractive for users that wear glasses.
The old Olympus SLRs such as the OM-1 and OM-2 definitely gave you a large image, but they were tough to view through glasses. The trend over the last twenty years has been toward higher eyepoint viewfinders, but like a lot of things, there's good and bad with it.

okay, so lemme get this straight. i don't wear glasses so the eye point issue shouldn't be a problem for me going from my F80. but, the image i see will be smaller because of the APS-sized sensor? i suppose that makes some sense (assuming they can't compensate with the mirror pentaprism), but i dunno how i will be able to compose my shots as well that way. do people find this annoying? or is adjusting easy?

I have been wondering about the eye point measurement myself. I used to work in a camera store where I had the chance to play with several different SLRs that were on the market then. I thought nothing much of the viewfinders until I picked up the F50 that just rolled in and the image through its viewfinder was significantly larger and brighter than any of the other SLRs. It was awesome and made the camera a real joy to use.
This message thread peaked my interest so I just ran off and checked the F50 specs and it indeed is listed as having a 18mm eye point!!
So on this basis I would say that the D70 will display a nice big image through the viewfinder. I am very happy about this and hope my analysis is correct.
I had a brief chance to look through a D100 in a store and noticed right away that the viewfinder was not as big or bright as the F50, and it is listed as 24mm.

Hmmm...reading many of the posts in the penta-mirror versus prism thread I found it generally agreed that the eyepoint and the image brightness/size are not really related - so unfortunately the last post could be overly positive. Looks like D70 viewfinder may be lacking in several ways.
