iPhone 5S, 5C
Announcement Date: Sept. 10, 2013
In an unprecedented move, Apple unveiled not one but two iPhones at its Sept. 10 event. The iPhone 5S comes in gold, space gray and white, with fingerprint identification capabilities, and it's supposedly the fastest iPhone yet.
The second device, the 5C, is designed as a budget phone that comes in a variety of bright colors. Apple also released its iWork software free with the phones, appealing to the growing BYOD trend. Since the latest version of the iPhone was released a week ago, shares of Apple have fallen more than 11 percent.
