I don't even like the idea of it. I think it removes an important aspect of UI that has until now been so entrenched that we take it completely for granted: pressing 'enter' signifies the completion of input. In a conversation between humans, it's considered rude to begin responding to someone before they're finished talking. This behavior is more than just an interruption; it ignores the full thought intended by the speaker in favor of an assumption. Interacting with software is no different; even if the conversational dynamic doesn't directly apply, we still have similar subconscious expectations. I don't want a response until I press enter. Before that, I'm in the process of constructing my search terms as I type them, often revising them, expanding them, and correcting typos. Besides all of that, Google is now executing several queries for every single query that would have been provided previously. Most users are probably not even going to look at the results until they're done typing, so this is probably a significant waste of bandwidth and CPU cycles that could be put to better use.
