Yes, of course it is, but I dont see why you cant slate microsoft for realising such a piece of crap. if theyre going to do it that badly, why bother spending money on getting a team of people to make it anyway :( im far from being a mac fanboy, im sitting on here happily using my dads athlonxp machine while my mac mini sits serving movies under the tv, so dont try the whole hating microsoft ploy on me.
but mac messenger is yet another inferior microsoft product!
