re: I like the iPhone 6, but it is too delicate

The key scratches happen with any phone that has an oleophobic coating. They're small scratches that don't affect the glass itself and are only visible under harsh lighting, but they tend to drive my OCD nuts. Thank god for cheap tempered glass screen protectors.

Honestly, we should all just accept that we're carrying thin computers with glass screens in our pockets every day, and treat them as such. The bigger they are, the harder they fall. My iPhone 4s got scratched and scuffed to hell, but it took many hits to the pavement without even cracking. I can look at my twice-as-big Nexus 6 and know without question that this surface area of glass would not withstand the same kind of abuse or impact. Yes, engineering and materials used will play a role in durability, but not as big of a role as physics and luck.
