I own two D800e's and they are simply outstanding cameras. In the past, I've shot with Fuji Pro-S1, Nikon D1x, Nikon D2x and Nikon D90. The Nikon D800e blows away all of the above.
Professional camera from the build to the image. It is in the class of medium format camera and has the highest rating of all sensors for quality (95 DXOmark)
As far as low light capability, it is usable to 2200 ISO for the type of photography I do (Weddings and Events). After that you start to see the noise, however I think it is a pleasing noise and looks like what you would get from film. It is considered one of the better low light cameras out there. The D4 is only slightly better.
I believe that the D800e will last longer than any other camera I have purchased (from feature point of view), so now I can concentrate on putting money into lenses instead of upgrading cameras on a 3-year cycle.
As far as size of output, I shot raw lossless compression which is around 45MB, at Raw uncompressed it around 70MB and TIF up to 200MB, but on JPEG goes way down depending on quality and size. You can also crop in camera to DX and so forth. So this is not an excuse in my opinion. The camera simply produces outstanding photographs, but you do need good glass and if you hand hold, good technique.
The dynamic range of the camera is 14.4 EV, which is huge and the best measure by DXOmark. Another reason to go with this camera.
The cost difference between the D600 and D800 is not enough in my mind to justify not going with the D800.

Unless you are willing to pay top dollar for a UV filter, then I would go without. I never ever shoot with one and only buy top quality ND and other filters (LEE).
You spend a ton of money for a good lens, why put a piece of crap in front of it...just for "protection". BTW, what are you protecting it from?
I use the ColorMunki Photo, it is in the $450 range, but is an excellent product. Calibrates the complete workflow from camera, computer to printer.
In the past, I've used the Spyder, which was ok, but I find the ColorMunki a better system for my needs.
The ColorMunki Smile is a new product and only calibrates the monitor. IMHO, it is the output that is very important for color matching.
