You are talking about Suggestions which is an entirely different feature than auto-refreshing of search(though both use ajax so I could have used a better description in my OP). I personally love Suggests as much as you.

What I hate is when I type, say a few letters of my query, and begin seeing frivolous search results begin to appear. I hate when I hit the back key, often it takes me to the previous page or simply removes the last letter from my query and updates the results. I hate when I begin typing an obscure name I just found from another query and see it disappear after I have typed a couple of letters.

I was just fine hitting the "return" key to pull up search results.
