I think your post does a disservice to those who chose the D700 (and D300) and prefer their control layout and AF system.
There are good practical reasons why I liked that arrangement - primarily for familiarity when used alongside a D3s. That was the main reason why I didn't replace my D700 with a D800 - but went for a second D3s instead.
As for AF points, we're not all sports shooters! Having a greater number and spread of sensors is very useful in portraiture, where it's easier to put one of them exactly over one eye whilst still getting the framing you want.
For most, I would suggest, it's not a question of "ego" but of practicality.
I'm not against the D600 per se - I may get one as my travel camera, where compatibility with the D3s is not relevant. I love the idea of the D800 too - maybe a pairing of D800 and D4 lies in my future... when prices come down
