Just curious, what you think is the best mail client for windows and/or mac?
thunderbird->windows?
entourage->mac?
I threw outlook in the trash… total crap. the filter sux big time and its slow. I love thunderbird’s! easy to train! 
In Outlooks defense (which is admittedly slow), if you use even half of it’s features you’ll quickly realize that there isn’t a single app on the market that matches it. On the other hand, if you fall into that large majority of people who just want to read their email the app is pretty heavy.
For Windows, if you’re on Vista, Windows Mail is pretty good. In my experience it’s faster than Thunderbird and it handled Gmail’s IMAP better.
