She's a little bit country, he's a little bit rock-and-roll.
Canon makes nice digital SLRs, no doubt. But like somebody else said, there's something about the color depth on the Nikon sensors....
I like Nikon's ergonomics (button placement) and in-camera software more too. And can you reprogram the Canon buttons? Like sometimes I switch my exposure/focus lock with my shutter button. I won't go into why here, but that sort of flexibility is a huge plus for me.
