>I would consider PR4 and PR7 as hugely different. Not so evident when looking at the direct affect on rankings (as other factors tend to be more important), but very evident when it comes to the other uses of PageRank (roughly two to five orders of magnitude).

Yep. To put this is perspective for anyone reading, the home page of Webmasterworld is PR7. This site has got to have lots and lots of inbound links. Webmasterworld is quite an authoratative site. In contrast, PR4 is commonly seen with the homepages of teenagers. Getting a PR4 is trivially easy. The only way to get a PR7 is to have an impressive site, or through luck or skill manage to glom onto a link from a really high PR page. And almost always if you can it is a matter of skill. Of course, if you happen to be a close friend of Bill Gates... ;)
