I have not read the CNet article but in the real world it works in this way. If you want to draw a conclusion, you need a sample size that is "good enough" to make a judgement on the population. I believe CNet is basing that judgement based on a heat test conducted to one iPad only and the unit is not faulty.
Going forward, there has been efforts in gathering a more sizable amount of sample to draw a conclusion out of and we're using it on a issue-to-production-batch basis.

So far from community efforts (discussion forums from fansites like marumours to apple discussions), heating issues on Production Week 2 and 10 is trending upwards as more people are aware of the issue and are joining these efforts.
