Google Search
In concert with the Google Instant launch, Google disabled the ability of users to choose to see more than 10 search results per page. Instant Search can be disabled via Google's "preferences" menu, but autocomplete-style search suggestions now cannot be disabled.  A Google representative stated, "It's in keeping with our vision of a unified Google search experience to make popular, useful features part of the default experience, rather than maintain different versions of Google. As Autocomplete quality has improved, we felt it was appropriate to have it always on for all of our users."
