Hey, I'm completely new t the laptop world, and I see here the function Sleep. What exactly does this do and how long does it take before it goes into sleep? I suppose it uses less battery, but how much less? Is it almost the same as if I turned it off? How long does it take the harddrive to 'park' itself? Is it safe to transport my laptop in sleep modus? I find the idea of closing the lid (and putting it in sleep like this) and transporting it, extremely nice, but don't want to break the laptop by not being fully aware of what sleep does exactly... Thanks! Ps: The macbook & OS X are awesome!!!! PPS: ANy way to click an icon and 'delete' it without having to right click on it to send it to trash? On Windows you'd select it and press the delete button..
