The MacBook Pro is a line of Macintosh portable computers introduced in January 2006 by Apple Inc. after they have successed in Power Book G4
They have been designed two body,both of them are made of aluminum. First design is coming out with 15'' screen and the second is coming out with 17'' screen The second "unibody" model has a more tapered design with most of the casing made from a single block of aluminum. This design was introduced with the 15-inch MacBook Pro in October 2008, along with the 13-inch aluminum unibody MacBook. The 17-inch model was updated with the same design the following January, also introducing the built-in battery that was later used in the rest of the MacBook Pro line from June and in the regular MacBook from October 2009. Apple updated the unibody line in April 2010 with Intel Core i5 and Core i7 processors in the 15- and 17-inch models, while the 13-inch models retained the Core 2 Duo processors.

I thought, Mac Company is a great company.They present alot of items that have a high quality and also the price is not too high. They always discover many new things that people want, they also successed of the marketing.
