Perhaps a move away from apps to widgets -- users will continue to be impatient with anything other than the fastest way of getting things done on a device. So rather than launching an app, reaching a home screen and then selecting an option from there, apps will provide direct links to specific actions that can be invoked from the OS. For (a simple minded) example: you don't launch the Twitter app to tweet, you invoke the 'tweet' action. And possibly, the concept of API's might hit desktop environments and we might be able to string together such actions much like we do with UNIX piping, allowing for more automation (e.g. 'append this text to document x with time stamp', where the doc is rich text document)
