Microsoft has bundled a lot of its online properties under the MSN banner.  Offerings include e-mail (Hotmail, Hotmail Plus and Outlook Live), IM and Blogging, Search, Internet Acess, Entertainment, and Mobile.

Microsoft Office Outlook 2003 is an online version of Microsoft’s bloated Outlook desktop email product.  Hotmail Plus offers more in-box space and larger attachments.

Instant Messaging & Blogging
offers MSN Messenger, and MSN Spaces.  In my opinion, MSN Spaces sucks balls.

I will not describe the others here.  Check them out yourself.
