Starting at the end of 2012, I was not happy with the direction Apple had gone in under Tim Cook. I didn't find the iPhone 5S too impressive, the iPad Air was just a stretched out iPad Mini, I didn't like the look of iOS 7 ( but found it bearable) , and I considered the iPhone 5C the worst new Apple product of the 21st Century. However, the iPhone 6 changes my opinion considerably. I was about to go with a GS5, but decided I would reconsider and wait till the iPhone 6 was announced. So, I got my hands on it early and I was very impressed. Unlike most phones of this year ( GS5, HTC one M8, etc.) , the iPhone 6 takes a completely new design and makes the iPhone 6 still comfortable to use with one hand. With an improved screen size and great design amongst my pros and cons, I consider the iPhone 6 a worthy upgrade for any users on the 4S or 5/5C, but for those on the 5S, wait a bit for the 6S. The iPhone 6 is the best iPhone, in my opinion, since the iPhone 4 was released in 2010.
