Those are my top two picks for Outlook replacements. There are others, of course, most notably Thunderbird (though ), Windows Live Mail (ditto), and .

On the other hand, are desktop-based PIMs/mail managers even necessary anymore? There's a strong argument to be made for keeping all your data in your phone and synced to the cloud, without the hassles of desktop software. Obviously there's no one-size-fits-all solution, but I'm curious to hear which one works best for your situation.
