iPhone Hardware System Review 2;4

          Steve Jobs and the Apple company broke the mold on June 29, 2007, when the first iPhone was released, and the company has not slowed down since.  The first generation iPhone was the first completely touchscreen cell phone, with a sleek look and neat features that made it the hottest must-have accessory of its time.  One of the best features of the iPhone was the camera quality, which was a huge step up from its flip-phone competitors. The iPhone has since seen nine generations, with the last release being the iPhone 6S in September 2015.
          On the first 5 generations of the iPhone, the screen was 4.5 inches, and then changed to 5 inches with the release of the iPhone 5.  A half inch made much more of a difference than one would think.  From my personal experience as an iPhone owner, the 5 inch model was the best one.  I had a 5, and loved the bigger screen, but now with the 6, I find the size a little too big at 6 inches. I often find my thumb sore after a good lock-in of Facebook, Instagram and texting.  One aspect of the iPhone system that is always an improvement is the camera.  The original iPhone's camera had 163 ppi (pixels per inch), as compared to latest 6S's 401 ppi.  The quality of photos is exceptional, although I have to say it is not as good as that of the latest versions of Galaxy's.
          In the beginning, the iPhone's biggest competitor was the BlackBerry.  In my experience, iPhone's were too expensive, with the original generation costing a pretty penny at $499, and was considered a luxury item.  For young people especially, the BlackBerry was the more economic choice.  The feature BBM was hip and brought texting to a new level.  iPhone was lacking in the area of messaging until they introduced iMessage with the release of its OS X operating system on the iPhone 5.  Once this feature was added, the iPhone took the forefront of the smartphone world. 
          While watching the iFixit Video's teardown of the iPhone 6S, I found their critiques of the phone pretty petty.  They said customers were unhappy with the camera being "bulky" and not flush with the phone, and also the two stripes at the bottom that provide the phone with better service and wifi access, as not attractive.  Who cares about two tiny stripes that will probably get covered by a case anyway? And the camera also becomes flush when you put on a case, which almost every one does.
