What's the difference between Macbook, Macbook Pro and Macbook air?

Q. I am looking to buy a mac and I wanted to know what the difference is between the new Macbook, the Macbook Pro, and the Macbook Air. And if there is not really a difference then which one is better. I am a student so I wont be using it for other things like gaming. Just social networking and school work, surfing the net, and downloading music, and burning movies.

A. The main difference in the 3 computers are the processor and the casing.

Macbook is not made of aluminum but more like a hard plastic. It has a slightly slower processor and you can only upgrade to 4GB of RAM.

Macbook Pro is made of precision unibody aluminum enclosure. The processor is one of the fastest you can get in a laptop. The screen bezel is also black to make the screen color pop and make watching movies more enhanced. It includes a SD card slot, Firewire 400 & 800. The RAM is upgradable to 8GB.

Macbook Air is very light and thin. Good Processor and great keyboard and screen that's similar to the Macbook Pro. However, no firewire and no DVD drive is a major drawback for someone who wants to burn movies or create movies by importing DV video.

For a college student, I highly recommend the Macbook Pro 13" or 15".
