Operating System

• Many of the differences between Android and iOS are due to the relative openness of the operating systems. Apple has strict guidelines for interface design and limits the degree to which users can customize the iOS theme. Apple also forbids the usage of third-party code such as Adobe Flash in an effort to maintain stability. Both of these factors greatly contribute to the recognition iOS receives for its ease of use and elegance, but it also burdens those users who prefer to have unlimited control over their phone. Because Android is an open source operating system, users can customize almost every aspect of their phone. It is also possible to run Flash on the phone, allowing users to stream online video and play games. This flexibility is particularly appealing for those who like to tinker but it does lend itself to instability and inconsistency in the user experience.
  
  

Hardware

• Probably the most dramatic difference between Android and iOS has to do with hardware options. The only devices that run iOS are the Apple-manufactured iPhone, iPad and iPod Touch. Apple does not license the operating system for usage on other devices so if you want an iOS, you have to buy an Apple device. Android, on the other hand, is available on dozens of different smartphone and tablet devices manufactured by a variety of companies. The variety of options covers the full spectrum of smartphone and tablet configurations so that you can select a device that suits your needs and budget. Hardware variety also enables you to find Android-powered devices on all mobile carriers whereas the iPhone is only available on AT&T and Verizon as of August 2011.
  
  

Applications

• Android and iOS feature massive app stores where you can download and purchase apps, ringtones, music and games. Though the iTunes App Store is larger than the Android Market, both app stores are remarkably comprehensive and you can expect to find an app for every conceivable need. Where the app stores differ is in the availability of games. Some of the best reviewed titles are only available on iOS and it appears that game developers are placing more emphasis on iOS due to the stability of the platform and the perception that iOS users are willing to spend more money on games.
  
  

Multimedia

• One of the biggest advantages iOS has over Android is iTunes. The iTunes store enables you to easily purchase music, audio books television shows and movies straight from your iOS device. You can also easily manage your podcast and video subscriptions from iTunes. Android users can purchase multimedia too, but the market places for multimedia are fractured across a number of different providers.
