I do money online. So for me sales are important and is the only relevant and most used indicator.
As long as I make sales ( and I do ) with pages that have from pr 0 to pr 2 ... the rest is not important.
Sure I can't brag about my pr ... but I can take some money from the account to prove my work

Page rank is important for the web site.It specifies the quality of the site. If you have higher traffic, automatically you can heve more visitors to get back links from you.So, both traffic and PR is important for the web site.

PR is helpful for links selling and get links from relevant sites (link sharing)

I have seen many site with 0 PR but have more traffic than PR 4 site in my view traffic is more than PR site gain PR with the time pass.
