Why is Black more expensive than white?

It's black that is why it cost more. All the MacBooks are made of plastic. I don't know if it is more durable than a pro but mine is very well made and at 16 months old looks as good as the day I got it.

The black MacBook has way more specs for example it has a super drive rather then just a combo drive.. more ram..more memory etc. PLease see the link for info!

Just scroll down a bit and it breaks it down for you!

The OP was not comparing the BlackBook to the low end WhiteBook. His question specifically was aimed at the high end WhiteBook compared to the BlackBook. If you add the 160 GB drive to the Whitebook so the specs are the same the BlacBook still cost 125 dollars more. Hence your paying more for it being Black. In my opinion the Black is well worth it.

Check the link out you gave. All three come with one GB of RAM so your statement about more RAM was wrong. The only difference is the BlackBook has a 160 GB drive compared to the 120 GB drive in the high end WhiteBook.

I missed that part I apologize but don't demean the whole post as I was providing helpful information.

I was not demeaning the whole post. The link you gave gives some good information.
