One of my sites lost a great set of sitelinks. Wah!
However, it seems to me that some of the characteristics of personalized search are creeping into the general SERPs. I have a couple computers that are never used while logged into any Google service. The SERPs that I see on those machines are starting to remind me of how my logged-in SERPs behaved when personalization was first rolled out.
I think that the days of standardized SERPs are gone for good. Everyone will see something different now. Will be really hard to know your true rankings.
