[X4U] Tiger Mail, SmartFolders or Rules?

[Eric Prentice]

In mail I've made extensive use of rules. Over 100 of them sorting  
all my new mail into bunches of folders based on criteria like what  
company the message is coming from, if the sender is in my address  
book, what account the mail is coming from.

I'm wondering if it make sense to convert the rules that are simply  
putting the messages into a certain folder into Smart Folders.

In one sense, it seems like smart folders would be a better way to  
keep things clean and speed up the processing of incoming mail. On  
the flip side, it seems a little crazy to have all my mail sitting in  
one folder.

Any thoughts?
