Although saying that, why not just set up browser preferences to block the Google cookie? Although i have a feeling Google would tell you to turn them on before allowing access.

Edit: Just blocked cookies for Google, in FF, but still drops a cookie of sorts. Googd thing is, with the webdev tool bar, you can see what they've dropped and just remove them. Cool.

Still wanna have a gander at that tool though, i wanna see what porn sites i've been frequenting!
