Steve Jobs once professed to have "cracked" three markets he deemed to be key in Apple's progress. One was the textbook market, which has already become a reality with iTunes U. The next was the television market, which is hotly-rumored to be in the works for the not-so-distant future, while the third area was the photography market, which although affected by both the iPhone and iPad, has yet to be attacked by Apple in a manner which would back up Jobs' claims.
While nearly all of the social networks' official mobile apps are eclipsed by third-party offerings in terms of interface, functionality and user reaction, only rarely does an app truly set new boundaries in what it takes to be an exceptional app.
