Windows Live Messenger Beta

The Windows Live Messenger Beta, which will be a competitor IMs like Yahoo Messengers, Google Talk, is available for all to download. This new IM will replace MSN Messenger.
Key features of this IM include,
1.Folders Sharing: By just dragging-and-dropping, users can share files and photos with other users. Then a Sharing Folder, which can be accessed by both the users using Messenger, will be created on both the user's computers. I think this is a great concept which will replace sending files and photos as e-mail attachments or tedious photo & file sharing.

2.Video Conversation: Using webcams, users can video chat in full-screen video with good synchronized audio and video service.

Other features include Offline Messages (this feature is not available in MSN Messenger), Cordless phones designed for Windows Live Messenger, Windows Live Contacts etc.
