GN is clearly inferior in build quality to an iPhone, but you have to be a bit of a snob to call it "garbage". It's solid hardware.
It's only inferior in visible quality (I've dropped it a lot and it barely has a scratch on it), but I'm okay with that because it costs half as much as an iPhone, which I think is very significant.
You can get a top-of-the-line smartphone for $300. That's amazing.
Not sure why you think this. It is mid range phone by every benchmark (e.g. no LTE, battery life, screen quality) and it gets destroyed by the iPhone 5 and Galaxy S3 in every performance benchmark.
I've dropped mine (which does not have a case) from chest-height onto brick, down a flight of stairs onto tile, and onto the road while biking at a moderate speed (maybe 15-20 km/h). It has some dents on the side but the screen is totally fine. I rather doubt the iPhone would survive the same.
