Google seems committed to get the whole search experience better and faster for the searchers. It seems Google has this love affair for the speed. Not so long ago, it introduced Google Instant and then it introduced mod_pagespeed to accelerate the website loading speeds.
Now, Google has released Google Instant Preview which I think is incredible for searchers. It actually poses a challenge for website designers to make the websites appealing to get the first impression count. The Google Instant Preview would definitely affect the click through rates but you really need to have your website up there to make any difference at first place.
