IE 8 did something to Google SERP

I found this weird thing accidently. Googled 'vitamins' on Firefox and Chrome, I got same results with a lot of sponsored links. But googled it on IE 8 beta, I got totally different results. Clicked on one result, it directed me to another SERP. Most importantly, none of sponsored links showed up. My IE 8 version is 8.0.6001.18241. I don't think it's IE's bug. My guess is MS did something to its top competitor on its new browser. Correct me if I am wrong. Try it and let me know whether you see the same phenomenon.
