Nikon and Canon are both about the same in terms of value and price, some offerings are lower some are higher. Nikon offers a 5 year warranty on their pro glass, Canon a 1 year. I think people should look at what each company has to offer in terms of product options and choose the one that best suits their needs and wants that way.

I went with Nikon because their range of lenses appealed to me more than Canon's. As for bodies, eh, they come and go. Both companies jump back and forth as far as who has the better product at any one time but neither is leaps and bounds better then each other at any one point. If you can spot a Nikon picture over a Canon picture you are seeing things that the 99.99999999998% rest of us can't.
