Re: How often does Google Update PR?
I love PageRank discussions. Not kidding you. What I love most in those discussions is what people understand about page rank and their comments if it is important or not:

But, Google looks at considerably more than the sheer volume of votes, or links a page receives; for example, it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important." Using these and other factors, Google provides its views on pages' relative importance.
Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines dozens of aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query.

PageRank also considers the importance of each page that casts a vote, as votes from some pages are considered to have greater value, thus giving the linked page greater value. Important pages receive a higher PageRank and appear at the top of the search results. Google's technology uses the collective intelligence of the web to determine a page's importance. There is no human involvement or manipulation of results, which is why users have come to trust Google as a source of objective information untainted by paid placement.

My resume:
PageRank is an algorithm which assigns every web page a score that indicates how important a page is. And the importance of a page is calculated based on the importance of all other pages that link to it and from the number of links each of the other pages have. And some information I got recently, in their PageRank algo they included their site quality guidelines requirements.
Here is a side-info about this: Webmaster Help Center - How can I improve my site's ranking?
Because I love PageRank so much and I care about if more than ever, I have setup on our server this tool PageRankBot - Supplemental Results Detector (SEO Tool) and I want to install when I have time the desktop Java version. Reviewed by a handful of high-profile players in the SEO industry including Aaron Wall, Andy Beard, Dan Thies, Red Cardina. Should myself and all others be ashame of ourselves? 
After all, are you very sure that PageRank important to you?
