No, it does steal more. Whatever your monitor size the instant suggestions should steal enough space to knock out an organic result.
It's a damn shame there isn't anything like, say, a scroll wheel or a scroll bar, to look at the results below the fold. That would really sort things out.
I bet small monitors DO have an effect, and small monitors + instant is probably worse.
But what that effect is exactly, that's harder to say. It's not quite as simple as the OP seems to think, IMHO.
