The new experimental page changes that. As you scroll, both the search bar at the top and links down the left side scroll with you. That way, you can easily update your search term or refine the search from wherever you are on the page without having to scroll back up to find them.
See the experimental design of new Google search results page.
As the video above shows, Google may keep the pages links at the bottom of a page, but combine it with the always present search bar and links. The other change is the preview functionality that now has a clickable spyglass appearing to the side of the text block link rather than next to the link title.
When and if this update becomes the standard for Google Search is in Google’s hands. Everything seems to work, and the infinite scrolling is definitely an improvement.
