Frankly IMHO the worst decision Nikon have made with the D700 is to incorporate the on-camera flash. Not because the flash is a bad idea, quite the opposite there are a number of advantages. But the reason it's a bad idea is because they've had to trade off the 100% viewfinder and settle for a 95% viewfinder. Now even that isn't really bad at all but it's being picked over like a three week old corpse on this forum as a HUGE problem.
To me the ability to have a built in CLS commander with the built in flash instead of having to buy another SB-800 or an SU-800 outweighs the viewfinder area loss.
For those instances that 100% view is critical Live View works great. If I'm framing so carefully that the 95% is a problem my camera would be tripod mounted and I would be working slowly enough that Live View would not be a handicap.
