The Importance Of A Competitive Search Market

With regards to new interfaces (voice/visual/whatever) that people sometimes say will be the "next big thing" in search -- these are just features that Google can easily implement if they prove to be so effective (which they probably won't -- I'd much rather type in my query than say it). Replicating the sophistication, performance and scale of Google is much harder.
Anyhow, Cuill and Powerset both have scope to make systems which are more efficient and could therefore be supported by less intrusive advertising. The switch from AltaVista to Google was influenced by the intrusiveness of advertising. Perhaps this consideration would inflence a subsequent transistion.
I'm reminded of Scotty's attempt to use a Mac in Star Trek 4: The Voyage Home ( http://www.humaninterface.org/blog/archives/scotty.jpg ). Who could be happy with current search systems after seeing any amount of science fiction?
