One of the greatest strengths of Dropbox is the large number of platforms its supports. Personal computers running Linux, OS X and Windows are all supported. This would normally be considered very good, but Dropbox takes things a step further by offering support for mobile devices.

The mobile devices currently supported include Android smartphones, iPhones and iPads. Support for Blackberry has been publicly announced but not yet finished (as of November 2010). All of the mobile Dropbox applications are every bit as free as the PC client and provide full functionality - although the types of files that can be successfully opened on your smartphone will depend on the smartphone's software support.
