What is the difference between normal macbook and the more expensive black and white macbook?

Q. What are some of the main differences between the one that cost about thousand dollars and and the one that is four hundred dollars more. Please do not tell me to go to the site because I didn`t discover much.

A. The more expensive models come with the following hardware upgrades:

2.4GHz processor (vs. 2.1GHz for the lower end model)
2GB of memory (vs. 1GB)
250GB hard drive (vs. 120GB for the lower end model and 160GB for the mid-range)
DVD/CD writer (vs. just a CD writer in the lower end model)

Hope this helps!

What is the difference between a MacBook pro and a MacBook pro with retina display?

A. RETINA DISPLAY = claim a high enough pixel density that the human eye is unable to notice pixelation at a typical viewing distance.

What is the difference between MacBook Air and MacBook Pro?

Q. So I want to save up for a MacBook for my 15th birthday this November. I just want to know which one I should get... MacBook Air or MacBook Pro? What is the difference? Please explain.

(I put this in a popular category to get more answers, I know its the wrong category).
The MacBook Pro is much more expensive, why is that? What's better about it?

A. Air: Hellofva light ligher than the Pro. Less "bulkier" (the Pro isn't bulky at all to begin with). Doesn't have a CD Drive

Pro: Bit heavier, has a CD drive.

Other than the a few physical components, they're essentially the same thing.

Edit*:

The Air is more expensive for the pro. The Price you were looking at was the price for the 11 inch air, which does start at $999. But when you compare the price of both 13 inch laptops, the price for the Air is $1299 vs. the Pro which is priced at $1199
