Let's examine what you think "simple logic", and "established facts" are.
First you claim "Sensors hardly seem to matter to the majority of camera buyers, at least that is what the global market share data have been saying for years."
So, you're claiming that Sensors don't matter to camera buyers, because the majority of cameras sold use overwhelmingly lower quality (smaller, inferior, low end, however you want to frame it) sensors. In your mind, this is an established fact, when in reality something like... oh I don't know, price might be a more significant driving force in camera purchases than anything else, but that sensor quality might still be very important. The mere fact that most cameras sold use lower quality sensors does not equate to any consumer stance on sensors at all.
Then you let off this gem: "Or more correctly, the differences between Canon’s sensors and their competitors’ are irrelevant as far as most camera buyers are concerned."
Which, logically, is just as stupid a conclusion as your first statement.
Either you're a troll designed to generate more postings here via conflict, or you're a complete clown. Either way, I'll just ignore your babble from here on out.
