The MacBook Pro (sometimes abbreviated MBP)1 is a line of Macintosh portable computers introduced in January 2006 by Apple Inc., now in its third generation. Replacing the PowerBook G4, the MacBook Pro was the second model to be announced in the Apple?Intel transition, after the iMac. It is the high-end model of the MacBook family and is currently produced with 13- and 15-inch screens. A 17-inch version was available for sale in April 2006.
The first generation MacBook Pro appeared externally similar to the PowerBook G4, but used the Intel Core processors instead of PowerPC G4 chips. The 15-inch model was introduced first, in January 2006; the 17-inch model followed in April. Both received several updates and Core 2 Duo processors later that year.
The computer's second generation, known as the "unibody" model, has a more tapered design and a casing made from a single block of aluminum. It debuted in October 2008 as the 15-inch MacBook Pro and the 13-inch aluminum unibody MacBook. The following January brought the design to the 17-inch model, along with the built-in battery that joined the rest of the MacBook Pro line in June, during which Apple also absorbed the unibody 13" Macbook into the MacBook Pro line. Subsequent updates brought upgraded Intel Core i5 and i7 processors and introduced Intel's Thunderbolt technology.
MacBook - facts from Wiki
The MacBook is a brand of notebook computers manufactured by Apple Inc. from early 2006 to late 2011, and relaunched in 2015. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple-Intel transition from PowerPC. Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the powerful MacBook Pro,3 the MacBook was aimed at the consumer and education markets.4 It was the best-selling Macintosh ever. For five months in 2008, it was the best-selling laptop of any brand in US retail stores.5 Collectively, the MacBook brand is the "world's top-selling line of premium laptops."6
There have been four separate designs of the MacBook. The original model used a combination of polycarbonate and fiberglass casing which was modeled after the iBook G4. The second type was introduced in October 2008 alongside the 15-inch MacBook Pro; the MacBook shared the more expensive laptop's unibody aluminum casing, but omitted FireWire, which hurt sales.7not in citation given A third design, introduced in late 2009, had a polycarbonate unibody casing and no FireWire ports.
Advantages of laptop
Portability is usually the first feature mentioned in any comparison of laptops versus desktop PCs.46 Physical portability allows a laptop to be used in many places? not only at home and at the office, but also during commuting and flights, in coffee shops, in lecture halls and libraries, at clients' locations or at a meeting rooms, etc. The portability feature offers several distinct advantages:
Productivity: Using a laptop in places where a desktop PC cannot be used can help employees and students to increase their productivity on work or school tasks. For example, an office worker reading her work e-mails during an hour-long commute by train, or a student doing her homework at the university coffee shop during a break between lectures.
Immediacy: Carrying a laptop means having instant access to information, personal and work files. This allows better collaboration between coworkers or students, as a laptop can be flipped open to look at a report, document, spreadsheet or presentation anytime and anywhere.
Up-to-date information: If a person has more than one desktop PC, a problem of synchronization arises: changes made on one computer are not automatically propagated to the others. There are ways to resolve this problem, including physical transfer of updated files (using a USB flash memory stick or CDRs) or using synchronization software over the Internet. However, transporting a single laptop to both locations avoids the problem entirely, as the files exist in a single location and are always up-to-date.
Connectivity: In the 2010s, a proliferation of Wi-Fi wireless networks and cellular broadband data services (HSDPA, EVDO and others) in many urban centers combined with a near-ubiquitous support by modern laptops48 means that a laptop can have easy Internet and local network connectivity while remaining mobile. Wi-Fi networks and laptop programs are especially widespread at university campuses.
