Not that I'd use anything Microsoft except for 64 Bit XP
That's silly because it's less stable and more vulnerable than Win 7 and far less compatible with current hardware. I've been programming Windows at both low and high level software since Win 2.x and Win 7 is without a doubt the best there's ever been.
Regardless, the Windows we knew is now gone with Win 8, so goes Messenger, and many other traditional MS brand Windows programs will probably follow suit as they attempt to adapt to the new paradigm.
Integration of Skype and Messenger is somewhat obvious and I think as MS tries to redefine itself as a mobile platform we're going to see more shifts in that direction and the old desktop is always going to be the loser in this transition.
