Google Preferences

Why must Google save my preferences in a cookie and not my account? I do not want my results filtered, and I want 100 results displayed per page. I cannot tell you the frustration I feel when resetting my preferences for the 15,000th time because Google is too stupid to save them in my Google account. When I log onto my account from any computer in the world, my Google results should reflect my preferences.

Cookies are not stable, and it's time Google realized that.
