Yahoo! has released some previews of its newly rebuilt Messenger application for Windows Vista. Yahoo! built this version of Messenger from the ground up, and uses pretty much all of features you are used to, but with a few little tricks. Features in the new Vista version include instant messages, voice, and video. Contacts from your Live Messenger can be added to Yahoo!, and you can see and interact with them as expected. Conversations can be organized with tabs through dragging and dropping. Of course there will be some added eye and ear candy with additional emoticons, sounds and interface customization. Yahoo! has a video preview of the Messenger application running in Vista, which you can check out here. Pretty cool! Yahoo has been really going all out lately trying to steal back some market share, and I’m sure they will steal some with this rebuild. Good job Yahoo!
