Hardware and design wise I actually do now hate the iPhone 6. It's the ugliest worst designed and worst built iPhone since the 3G and 3Gs.
I'm constantly dropping it when trying to pick it up due to the texture of the back of the phone and how slippery the edges are, it's a nightmare to pick up it really is. After watching an interview with Jonny Ives where he talks about the design of the iPhone 6 and why they jumped ship from the beautiful iPhone 5 and 4 look, he said it was to make the phone easier to pick up on a flat surface, because they apparently found in testing that a big phone like the iPhone 6 is very difficult to pick up on a flat surface. Now that sounds like a fair enough reason, the rounded edges do give you more purchase on the phone when your picking it up, that said... why did they then make it out of the slippiest metals on the market?! Like, how can they not have tested this and discovered this huge issue during development? Is it suppose to be a feature to help them sell more replacement phones??
On the build quality issues, am I the only person with stubble that when ringing someone gets said stubble caught in the space between the glass front and the metal sides/back? It's kind of insane and can be pretty painful to have facial hair unexpectantally ripped out of your face and then stuck in the side of your phone.
If you've never come across this and have a beard or stubble... just rub the side of your iPhone against your cheek or chin a little... It'll happen.
Jonny needs to go back to the Deter Ramms well and never come back to the iPhone 6's design, it's ugly and horrible to use.
