I am a big apple fun i have mac pro, a macbook, ipod classic etc.. all leopard...and i have a sony vaio laptop with vista business. Leopard in terms of network, sharing is a lot worse than vista. Leopard hangs many times too.... and what about a send to in second mouse click menu to send a file for exemple to a pen drive? Time machine is backup application. What about a system restore like windows?? In pro level windows 2003 Server is better many times than Leopard Server. So apple stop saying that leopard is better than vista and wake up and work to be better in all aspects!!!!!!
