I use Vista Enterprise and have no real complaints except that the screen saver has issues and locks up when you have an Anti Virus program running. Other than that no probs. I havent used the latest OSX but do have 10.4 on my Imac and I cant really say it is any better, and actually like Vista better than it. Ubuntu is ok If we are talking Linux I would say SUSE or Mandrake are better. Cheers
