The toolbar sometimes gives wrong or buggy PR data - I'd say that's the most common reason. Also, the toolbar shows old data, so the url may have been indexed, but then dropped.

The page might be cloaked to serve meta robots "noarchive" tag to Googlebot only.

Hmmm ... and there will be no way to confirm that either, with there?

Google does not export fresh cache dates on low PR sites at this time. You need at least PR6+ to get a cache date export.

I've seen an even more curious phenomenon:
A page has PR shown, is NOT in the cache but still ranks in Google! Now what is that? I always thought that if a page isn't in the cache it also isn't in the index.
And also: I have seen so many pages beeing thrown out of the Google cache/ index for the last two months or so. Anybody having the same experience?

Clicking to see the cache from the toolbar isn't the same as clicking the cache from the search results page. Clicking from the TB it often appears that there's no cache for a page, yet if you click from a search there will be.

It doesn't work like that. You can even use the meta tag <META NAME="GOOGLEBOT" CONTENT="NOARCHIVE"> to ensure that there's no cache, and the page will still be in the Google index and ranked with no "prejudice". That's very useful for time-sensitive information that you don't want to hang around after a certain date - sale prices, for instance.
