How about the semantic OS? I saw a demo today of ActiveWords which made me think of exactly this. We have become accustomed to not being capable of executing the actions on our machines without flipping through through menus or hitting a series of shortcut keys (I personally know more shortcut combos than I ever cared too). ActiveWords bypasses this by allowing users to customize actions in Microsoft's product by creating key words typed whenever and wherever to execute specific actions. Example: you're in Excel and need to search google.... simply type the word you correlate with executing a browser and directing it to Google, press the space bar a couple of times and boom, you're in Google. This is just one example of how users can customize their work patterns so as to not have to waste time or thought in how to execute specific actions.
