Gosh, oddly that's what we call people who whine about defective products which, if they had actually bought one, they could just return for a refund. Thus proving they are either trolling or are obsessive whiners. (and we're back on topic, yeah!)
There are two ways of viewing these people:
1) Perfectionists that are disappointed Apple fans where they expected more
or better and got less.
or
2) People who just love to whine.
Some of the videos which were posted on Youtube actually showed some pretty good examples of what they were talking about.
I always remember Hong-Kong where reception is amazing. I can be in the freakin tube going under water from Kowloon to Central Hong-Kong and have perfect reception where in the US I have to walk around my house to find a perfect area to stand in just to make a call.
