...it doesn't mean that my opinions are irrational.
Price IS an issue for me, and based on ALL factors regarding cameras, i haven't been too thrilled with Canon's releases.
Your opinion was quite rational, as was your decision to switch to Nikon. Personally, if my main purpose was to shoot landscapes, I'd be shooting with a D800, 14-24/2.8G and a PC-E 24mm. Put that in a fanboy pipe and smoke it.

The problem is when someone (and you're not the only one who does this) takes a statement like, "
I think the recent Nikon dSLR releases are much better than the recent Canon dSLR releases," and somehow translates that into, "
Most people think Nikon is dominating Canon." First off, your opinion is not everyone's opinion, or even most people's opinion. My opinion is not everyone's opinion, either, for that matter. That's why I often bring up sales figures - it's an aggregate way of assessing everyone's 'opinion' based on their buying choices. Sure, there are lots of factors that go into those buying decisions - features, cost, compatibility with current equipment, what their friends use, etc. But it's an objective measure, unlike all of the hot air (or electrons, as the case may be) that we read on internet forums.
Another problem is the evaluation of the camera in isolation, or worse, basing an evaluation on sensor performance alone. You state ALL factors regarding cameras, but both a camera and a lens are needed to take pictures. Sometimes, a flash is needed, too. It's the 'camera system' that takes pictures, not just a camera or a sensor alone. So, it's important to view it in that light - consider your overall needs and budget for a system, and buy accordingly. If one brand offers the best body in the world, but lesser lens choices, that's something to be aware of...
Finally, most of this really doesn't matter. Sure, there are a few examples of images that can only be taken with Canon vs. Nikon gear (MP-E 65mm and 17mm tilt-shift shots, ultrawide shots with an image-stabilized lens, etc.). But for the most part, it's much less about the gear itself than about the person using it to make images.
