High Quality Content by WIKIPEDIA articles! The MacBook Pro is a line of Macintosh portable computers by Apple Inc. that was introduced in January 2006 at the Macworld Expo. The MacBook Pro replaced the PowerBook G4 and was the second model to be announced in the Appleâ??Intel transition (after the iMac). The MacBook Pro is positioned at the high end of the MacBook family. There have been two designs for the MacBook Pro, both using aluminium. The first design was largely a carry-over from the PowerBook G4. The second "unibody" design is a more tapered design with most of the casing made from a single block of aluminum. The unibody design was introduced in the 15" MacBook Pro in October 2008 during a notebook-oriented announcement, along with the 13" aluminum unibody MacBook. The 17" followed in January at the 2009 MacWorld Expo, also introducing the built-in battery which was later used in the rest of the MacBook Pro line in June at WWDC 2009 and in the MacBook in October 2009. There are currently three MacBook Pro models, the 13", 15" and 17".
