Mac computer?

I’m thinking of buying a new computer, probably a laptop. I currently got addicted to the mac scrollbar/skin and its products. Is there an advantage of using mac over windows? Mainly for homework and dreamweaver/flash. :hr: If so, what?

I saw iBooks and powerBooks, they both look almost the same. Is there a difference?

and for the mac users out there, what do you think of macs?

Thanks :nerd:
