I really liked the 7D, it's a fantastic camera for it's day except for the very poor quality sensor. It was noisy at low ISO's and it lacked the micro contrast and sharpness of it's full frame brothers of the similar era. Every other part of the camera was excellent. It's handling and UI were a big step forwards for Canon. Certainly better than the XXD which pre-dated it. If there wasn't a 7D then I doubt the 5DIII or 1DX would have been quite as stunning.
Except that I would use present tense (the 7D still has a slightly crappy sensor but is a very capable camera in every other respect) I agree wholeheartedly!
