In other words, the importance of PR given by Google in SERP changes with different countries.
For me, it is a hell of a good way to diagnose my own pages, crawler access, link flow, and etc.
Okay... let's be clear.
PageRank - Important for rankings (i.e. numerical value of link juice)

I'm not saying don't look at TBPR
Google insists on displaying the 'Green Pixel Dust' in the stinking toolbar
The best way to think about it is that the number of pages that we crawl is roughly proportional to your PageRank. So if you have a lot of incoming links on your root page, we'll definitely crawl that. Then your root page may link to other pages, and those will get PageRank and we'll crawl those as well. As you get deeper and deeper in your site, however, PageRank tends to decline.
