Ah yes, I used to use Windows Live Mail myself because I had multiple accounts.
But now I just have all my Email address forwarded to my main one, and I have the option to send mail from any of my addresses all from inside the one account.
So I no longer need a Mail Client for something like that.
Between work and personal, I have five e-mail accounts running, I need a mail client. Plus, GoDaddy web based email will log you out after so long, I can't have that!
I use Windows Mail currently and I also use Gmail. I just have all of my emails that come into Windows Mail to be sent to my Gmail account so I can view them If I'm not home or if I am on my iPod Touch.
Windows Mail is my main email client. But each time I receive an email I have it automatically sent to my gmail so in case I am not here on my computer It will then go to my gmail where I can check it either on my iPod Touch or another computer.
I really like Windows Mail. I had set it up before I got Gmail, and also I don't want to switch my email address for everything that I use. Bit of a hassle..
