Alright, i've been thinking about getting a mac laptop for a long time... but i just confused myself with the following websites:

www.apple.com/powerbook
&
www.apple.com/ibook


now i read the descriptions and all.... but .... wth is the difference?

Is it just the fact that the two look different and that the iBook is a lot more simplistic in terms of layout?

Or is there some big difference i'm missing....
