new ibook user

[J. Brenning]

My dd recently purchased an ibook. We've always been PC people, so Apples 
and laptops in general are new territory for us. I have several questions I 
hope no one minds me firing off.

Is it okay to move a laptop while you're using it? I've always known not to 
move a cpu while it's on, but it seems, at least partly, the point of a 
laptop is the portability -- even while it's running. But what's to stop 
the harddrive from crashing? What about traveling in a car on a 
not-so-smooth road?

Also, when she turns on her laptop and looks at the screen, there are file 
folders showing. Is this the equivalent of the PC's desktop? If so, how do 
you file these folder to get them off the desktop and on as shortcuts?

Another thing is that when she downloads a program it seems to 
automatically unzip and install. Is this normal or is it because of the way 
something is set up?

Is ircle the only irc program for apples?

Is there a book or something that is recommend for newbie ibook users. Most 
of it we can figure out, but I'd like to understand it little better.

Thanks so much!
