I think the problem with electrical or electronics problems, is that a persistent issue in one subsystem can sometimes end up taking out additional subsystem(s). The problem might be isolated and never cause any other issues, but it seems like a pain in the neck to never let yourself forget to either turn off the camera or remove the CF card. Besides that, unless you're getting ready to replace it with the latest thing, consider that you can also tell Nikon to CLA the body too, for very little extra money. You'll get back a D700 that is perfect once again, which is a very good thing to have.
