Which email-client should I choose?

Gone are the days when we needed to login to Hotmail, Gmail, Yahoo Mail to check our mails. Email-clients have been around for quite a while and there has not been any one as popular as Microsoft Outlook. But with Mozilla churning out Thunderbird and Apple's Mail application, things have changed.

I personally am a MAC user and therefore prefer the built-in Mail application in OS X Leopard. But when I started using Microsoft Office: 2008 MAC edition, I noticed the changes in Microsoft's Entourage email-client for the MAC. It was colorful, neat and had notes, calendar, and my personal favorite 'MY DAY' built in. MY DAY is a short desktop widget if you will which displays events, reminders, etc. It is a cool tool to have and something which is missing in Leopard. But MAIL has its own elegance and charm to it. Simple yet productive. That is the key about APPLE, all its products have a simple elegance to it. You can't take your eyes off them. :). There I go again being a little MAC CRAZZZZY.

I want to hear from you guys, which email-client do you use? I know that offices and businesses prefer Microsoft Outlook, but what about you end users out there? Personally, for me these would be the ideal choices:

WINDOWS - Microsoft Outlook
MAC - Apple MAIL

Let me know what you guys think.
