I never intentionally search via Google while signed in to a G account. Still it happens, usually while I'm checking my AdSense stats or Google analytics stuff. It annoys me when I do that.
I normally use the cookie "exception" function for WW and 1 other site while I'm on those sites.
I do use Bing much more, but I have no illusions about where they'd go with this stuff if and when they choose to.
I sort of think of it as using the least invasive reasonably effective service available at the moment.
