This saves you the time at an average of 2-5 seconds per search and there would not be an additional load happening on the page.
At present, this feature isn’t available for iOS based mobile platform. Google has yet to make any official announcement on Google “Instant Previews” for this platform. But it has been spotted in action, and it could be a limited test roll out. So it is expected to arrive very soon on iOS powered Safari web browser. So you should be keep checking your Google search options on your iPad/iPhone and iPOd Touch.
