Apple unveils iPhone 6, other gadgets

Apple revealed the much-rumored iPhone 6 on Tuesday at a highly publicized media event. It is expected to be even thinner than the iPhone 5, which quickly became known for its less rounded design compared to previous versions of the iPhone. Along with the iPhone 6 will come the iPhone 6 Plus, which will have a larger screen, 5.5 inches compared to the iPhone 6's 4.7 inches. Both versions of the iPhone 6 will feature the forthcoming iOS 8, which will also be available for some older Apple mobile devices. Apple also announced the Apple Watch, another member of the growing smartwatch trend, that has also been the subject of rumors for some time, but just now confirmed. In a tie-in with the event, the extremely popular rock band U2 surprise-released their 13th studio album, Songs of Innocence, which was a long time in the making. The album was automatically downloaded for free to most iTunes accounts around the world, surprising many people who didn't remember buying a U2 album on the iTunes Store.
