Also, don't just limit your thinking to consumers. Consumers might need the next huge improvement to consider switching. Something to replace Google would probably need to give you a well researched and balanced report on your query, as opposed to just a fairly accurate link to something someone said somewhere. That's a HUGE leap.

Businesses on the other hand (rational ones anyway) will buy anything that exceeds a certain ROI, provided it meets certain requirements. There are so many ways to do this, but they aren't technologically sexy in the way consumer startups are. For instance, find a way to improve measuring their ROI! Then they're not guessing, you can point to exactly how much money they'll make/save. Improve something by 15%, then multiply that savings times the thousands of corporate users for one buyer. Viola, an upgrade license. Joel Spolsky is a master of this: see http://www.joelonsoftware.com/articles/fog0000000052.html There will always be more of a market for things like this.
