The main thing that is very noticeable is that cache data and exerts shown within the results do not always match. if you search for "foo widgets" you will be taken to the results page. The snippet on the results page will show "foo widgets" but neither the true page or the cached page will contain the same text. This can be fairly easy to spot if the serps link to a page that changes often, for example forums or news pages.
Back links are also not up to date with the main index, but this has been known for quite a long time. Page rank is difficult to judge. it is very possible that the data made public through the toolbar is not actually a true representation of a pages current value. It would actually make quite a lot of sense on Google's part to keep the current (true) data secret. By doing so they reduce the seo usability of the toolbar data.

Very rightly put. PR fluctulation are very frequent and backward links can't be judged.
Another thing that i would like to add her is(I feel it's related somehow but not able to corelate properly)Google is giving prefrence to the sites which are updated on a daily baisis or freuenetly. These newly introduced pages on contantly evolving sites are intantly updated and are finding nice ranking on SERPS.
