The next two additions to iOS 5: Safari and Reminders.
Safari on the iPad has become more like the desktop version, with tab support.
Reader is coming to IOS, where it belonged all along. As well, Apple’s Reading List basically brings Instapaper and Read It Later to iOS as a default feature. You can even tweet stories on your reading list, complete with autocompletes for @mentions.
Reminders is a way to keep track of to do lists and things to be accomplished. You can create lists of things and associate dates with the reminders, as well as locations.
Reminders will sync with calDAV and also iCal.
