Glad another person with an open mind tried the competition and discovered it's worthwhile.
I too am still caught in the Canon user interface paradigm and sometimes wish my D800's controls were easier to locate at times. More time spent with it and it's becoming familiar.
And I can trust the camera to be an excellent imaging tool that provides me with raw files that have far more adjustment latitude in post than anything I've ever shot with a Canon label on it.
Yup, more of my Canon gear is on Kijiji this weekend.
Once I sell some if it I'll be off to my local shop to see if I like the lighter weight and simpler control layout of the D600 better than the full-buffet of mechanical controls on the D800. I don't normally need much for customizable options, just the basics and killer raw IQ. And I won't always need the higher resolution and would occasionally prefer the slightly better SNR of the D600 over the D800 for low light work.
I DO miss the incredibly good live-view performance of my 5D2 for manual focusing in low light.
The D800 is disappointingly noisy in this aspect altho I found I can trust the focus rangefinder function to be very precise in most lighting conditions with any focus point i select so I can still MF with confidence.
Next I need to get used to Nikon flashes... They seem simpler.
