Not sure if many people have heard about this but basically its similar to Outlook Express as a desktop email client, you can use HOTMAIL with it though :D. I always hate opening IE just to visit hotmail and check my email.
I am very impressed and happy with MS for making this BETA and really look forward to the development of it, the good thing is that MSN Messenger opens it up when you click the mail button, so im happy with that,
Its only in BETA and you need to sign up to join the BETA and then in a week or so MS sends you an invite to download, heres some screenshots, its very nice!! :thumb2: :thumb2:
