ibooks?

I bought a ibook to use at school, its my first mac and I love it. I wanted a powerbook but they are so much more. All that apple advertieses are powerbooks. Are the ibooks still considered good? I bought best 12 inch ibook they have. I just want make sure I didnt buy somthing doesnt look good.

I think the iBook is awesome and much more rugged than the PowerBook. Good choice for being in school! Hope you enjoy it like I do
