The time is over... the announced MSN Toolbar Suite (Beta) is out today. 
Unfortunately at the moment (I'm at work) I've not the chance to install and try it, but for what I've see it seems really interesting. What I'm expecting on this tool is a great integration with the OS and a quick indexing and, obviously, for a complete evaluation of the product we've to compare it with other similar tools, such as Google Desktop Search and Yahoo Toolbar.
Who will win the Desktop Search war? It's Difficult to say now but... can you imagine what could happen if a day Microsoft will decide to distribute its MSN Toolbar Suite on Windows Update like a recommended upgrade?? Millions of automatic downloads will start...
