At the 2013 WWDC keynote, Apple unveiled iWork for iCloud. This service allows you to make full use of the iWork suite from any Web browser on Mac or PC. It's a great solution for people on the go.

In the coming weeks, Apple will unveil iOS 7 during the WWDC keynote and we can't help to keep speculating on its features. The question for this episode is: Which existing feature in iOS would you like to see Apple improve in iOS 7?
