I use a D7000 and I like it. Its loaded with lot of features, most I don't use though

(Not been sarcastic, but that's reality)
I am really getting hold of this digital photography in general, how pixels work..
For example, the Histogram of a jpeg on camera and Adobe LightRoom does not match (same photo) !!
I could clearly see the images appearing over exposed to "my eyes" and with LightRoom Histogram otherwise D7000 does show them only slightly skewed to right.
My life is so ruined !!

It will take time to really make a co-relation between couple of different display devices I use. My laptop, my PC monitor at work and at friend's place, my cell phone LCD, display of the person who might visit my Flickr photostream and what not and finally the D7000 display.
I read almost all the "WTS:Nikon D7000.." posts out of curiosity and assuming that the sellers are honest with the reason to sell, I see many many reasons (upgrades, shifted to Canon..) etc
It is true that in video reviews like cameralabs.com which I follow, it clearly claims that Canon 60D was giving better exposure results in bright sunlight to order of - 1 EV. That is too wide!
I think it is really necessary to understand the reasons, I am trying to read more and experiment. Many posts are claiming that D7000 is giving more emphasis on skin etc and over exposing the rest (or rather not giving other part of the scene any importance) to ensure keeping skin tones are proper...
More or less, I am feeling that its necessary to understand the behavior of the gadget in hand in particular circumstances to get the most of it...
Any helpful leads to better understand the Histograms are welcome
