Google, Give Me Back My “Backspace”

Google’s newest instant search ajax madness has completely broken the back button. If I am on a google search result page, and I hit backspace, it instantly focuses into the search box, and deletes the last character. Even if I click on an empty area on the page, and hit back, it again focuses on the search box and deletes the last character. Huh???

I mean seriously, there are 2 buttons on the keyboard that you should never mess with. The Enter key, and the backspace!!! Take my Q or X or something, seriously. Google, wake up, this is not what you are supposed to do. You are not better than the backspace!
