Watson Assistant in the Power of Your Hand

Today we completely expect intelligence to be in the palm of our hands.  We can get it, but the means at hand now is repeated search.  There have been a number of attempts, interesting but hardly complete.  I have been reading Scoble and Isreal's new book: Age of Context, which covers what this is expected to look like.  I have used Siri, but it has only been useful for the most 'hands free' moments.  Will IBM Watson provide solutions to the hand held assistant problem?  In particular because of its attention to natural language interaction?
