I would use Outlook if and only if they had useful email filtering. I like most items to go to my inbox, then I can apply my filters once I have read with an email. I find it harded to deak with email when it ends up in 50 different folders all unread. It is easy for me to miss something that way.

My only real complaint about Eudora's pay version is that it is an annual fee, and it is rather expensive at that. I'll stick with the free version and deal with the ads.
