The iPhone 5S. Apple is well known to be a leader in the market, but the 2 year refresh schedule is both a boon and a curse. In an industry which typically release major overhauls every 6 months, each iPhone iteration needs to be 2 years more advanced than anything else. This upgrade process is great for accessories which are given time to develop into the best in the world but means to innovate Apple needs to think outside the box. This iPhone 5S offers to change a whole lot without changing too much and most importantly the overall shape of the device remains identical. So your accessories are given top priority to remain just as great as they ever were Major Features: - Aluminum unibody design now with two new beautiful strips of delicately machined aluminum running along the top and bottom of the front face. Inspired by the long standing design of the iMac desktop the square glass and rounded aluminium bring unity to the Apple lineup. - Identical rear and side shape. - 4.2" IGOZ 1704x960 HD Retina display. Apple has done away with the dead space around the display and made the bezel smaller so your phone still fits beautifully and comfortably in one hand, the bezel is shrunk so your fingers don't have to grow. - Pressure sensitive home button strip. The home button is still there in spirit carved out of the lower aluminum strip but now the iPhone 5S uses a pressure sensitive pad with a seamless built-in fingerprint sensor, the strip at the bottom of the phone senses pressure and the center reads your unique biometric ID when you are pressing it, and takes the same amount of force to press as the iPhone 5's home button but will last 10 times longer and allows you to do away with the pass-code (if you want). - Proprietary sub-pixel processing algorithm so all of your old apps look crisper than ever, with or without updating your apps. Each iPhone 5S now has 9 pixels for every one that the iPhone 4 had. - GPU and processing speed have each doubled yet again, and the cameras each now produce half as much noise while retaining more detail. Stereo speakers inspired by the great results of the iPad 4 are integrated seamlessly into the existing lower cutouts.
