Hey Verge, build material IS NOT build quality !!
This website, like many others, is totally clueless and uninformed and keep on repeating the myth about 'build quality'. I guess they have a bias and an axe to grind.
Any 'plastic' device is automatically declared to have bad 'build quality' with no understanding of construction. Of course when said device comes from Apple, like the 5C, suddenly its fine because of magical elves and 'unibody'.
Never mind the facts about how resilient polycarb is and how many people have dropped their 'plastic' phones with no damage.
The word they are looking for is 'aesthetics', 'looks' and 'personal opinion', but hey, never let facts get in the way of page views.
