Apple iPod Touch

This product is remarkably similar to an iPhone but the iPod Touch starts at the same price as the iPhone 4S, $199. But it doesn't require a two-year contract with mandatory data plans. A contract free iPhone 4S is available in the market for $649.

People might consider an iPod as only a music player, but it runs most of the same business and productivity apps as the iPhone and it has the same size. The iPod's camera function can be used with popular apps such as Evernote for storing handwritten notes and other reminders, and its microphone lets you create easy to access voice memos.
