I think it's very ridiculous to suggest that a company immediately replace a thousand-dollar product because an arbitrary link on the internet suggests there might be a problem, without making any sort of diagnostic effort first.

If there were a widespread problem with NFC, and a large pool of internet reportage on it, sure, assume the worst. But at this point, I've heard one report claiming there's an issue, and one comment here suggesting there might be an issue, and my own experience with no issues at all.
