The logical, practical side of me thinks it is way too early for a hardware change to have been implemented. The skeptical side thinks they probably had someone look through several units until they found a couple they think the two of you will approve of.

I think the two of you will probably get some good units this time, but if you do I caution others to not take for granted that Amazon has found a real solution. Only when most of the people who receive replacements start reporting good units will I believe Amazon has actually fixed the problem.
