Siri paves the way for the display-less phone† - smaller, lower energy use
Context switching could be done like short-cuts: when you open an app it captures (most) shortcuts; and you can reallocate short-cut bindings. These are easy improvements. Just think of both voice and touch interfaces as having grammars.
Wolfram|Alpha's natural language interface is endlessly annoying for me - I think Siri would also get into trouble with more complex requests (but there's plenty of value in it before that limitation comes into play)
†this neologism could well go the way of the horse-less carriage
