Quite a few things seem broken right now, probably a side effect of the other changes Google is making. I'm sure it will be resolved soon enough.

Partial pageloads: I'm wondering if some of the discrepancies can be attributed to partial pageloads or "smart pageloads" where only a portion of the page is loaded/executed. If the analytics doesn't load the data is lost. If javascript is off the data is lost. If someone clicks outwards on adsense using private browsing some of the data (collected by Google toolbar etc) is lost. There are a lot of scenarios that can play out in which the data isn't saved, even people MASHING UP your site content via iframes because they only want to show "the_content" off your blog can cause problems.
