If Google really wants to "not be evil"... (Score 2, Interesting)

...in my personal opinion the biggest thing Google could do would be to have a personal preferences section and a "wipe my history" button. When clicked, this action would wipe out all of the data collected on me to date (by my cookie data, gmail data, etc).

That would probably be the single biggest proof that Google truly does stand apart from other all other companies.
