This is a ridiculous exaggeration. Less than 100 (and that's being REALLY generous) users out of thousands of shipping machines does not make the C2D "one of the worst products" Apple has manufactured in quite a while. People on Apple's discussion forum, where you're looking for many of your "examples," are there for the sole reason that they have a problem. It's like watching an emergency room, and then deciding that humans are in bad shape because everybody you saw there was injured. Without the context of how many happy users there are, these problems mean very little.
Indeed. Apple's products are by definition the best. Even if Apple offers a Core Duo 1.66Ghz Macbook Pro with Chimei LCD panels and 256mb of ram for twice the price of a top of the line Core 2 Duo Thinkpad, the Apple is still the best because the Thinkpad is not an Apple!
Anyway your metrics make 0 sense because the "vast majority" of the Apple user base are not even aware of the existence of such websites. Nor are they aware of Apple's 10 day return policies. Nor do they even know better to purchase online. Most likely they walked into an Applecentre and purchased it from there. When they didn't like the screen and brought it back to the genius bar all they will hear is "it is in line with specifications" and they will leave it at that. Then 3 years down the road when the walk past that shiny Vaio with that gleaming screen, they will reflect on their experiences so far (troublesome to get software, massive incompatibility, high quality screen) and guess what they will buy?
I am not looking at this from a "switcher's" perspective, but from a "switcheur's" perspective. Making any statements that this community does not reflect the user base may be true, but it cuts both ways. If anything the members of this community represents the early adopters, the crest of the curve, the well informed, the vocal minorities.
I just had an experience of chatting with a friend I bumped into who was in the market for a laptop some time ago, turned out that she got an Acer 5673. For less money than a Macbook 1.83 she got the same processor, lesser ram, DVD burner, the $1000 x1600 GPU (according to Apple's pricing methology) and last but not least, a brilliant screen. Now, I love my new MBP like the next guy, but the screen is really getting annoying.
Oh yeah, just to add, the Acer had a X1600, with 256mb, for less money, than a Macbook 1.83. Go figure.
