Using the PR metric to decide about using nofollow on a link is way down on the list. Most of the sites I link to in my articles when I talk about a website or reference some page, I actually don't use nofollow since they are usually good sites and I am linking to them in a natural flow of an article (I am not trying to send them PR for some sort of gain financial or otherwise).
To be frank I think nofollow is way over used now because everyone is running scared of Google. It may have made some link buyers etc rethink things but mainly it has hurt small and medium size websites. It annoys me when I see a relatively large newspaper website link to my content which they used to talk about in an article and they nofollow the link.
