What would any of you do if you were in the Electronics Research division on Apple's main campus, with the world breathing down your neck for even better features? You would start making cuts that the majority approves of. If I was blessed enough to be on that team and saw that 1% of people used ExpressCard, I would get rid of it too. The fact of the matter is that the majority of people do not use blu-ray, or care about it enough to justify Apple putting it in their products. It's not only a matter of making people pay for what they don't use, it's Apple's strive to make their customers happy. That's why they innovate and add popular features they think the public will like, because it makes them money. Right now, at least, the numbers aren't telling them to add blu-ray, even if this thread is. Apple doesn't have time to release a product outside of the labs against the odds and hope people like it.
They dont know that 1% of people use the EC. Id bet a paycheck that their "findings" wernt correct, their research methods wernt through, and they just flat out didnt to it right. Take a few Stats and research classes and youll know what im talking about.
