On October 14, Apple Incorporated hosted an event during which the company introduced their updates to the portable computers’ line, which includes the MacBook, the MacBook Air and the MacBook Pro.

Consequently, the redesigned MacBook, which is the cheapest of the three, is fitted with a 13.3-inch LED-backlit screen that enables users to watch videos and browse the Internet, 2.0 or 2.4GHz Core 2 Duo processors and also features Nvidia's 9400M GPU, a graphics processor that can enhance the laptop’s visual computing performance five times for 3D games and other apps.

Moreover, Apple’s portable computer weighs 4.5 pounds and now features a SuperDrive that has replaced the previous combo drive.

The 3-pound MacBook Air comes with a 13.3-inch LED-backlit screen, too, but its frame is much thinner than the MacBook’s one. It also features the Nvidia 9400M GPU and Intel Core 2 Duo processors that can clock a maximum 1.8GHz. The laptop has added a 128GB SSD option and a Mini DisplayPort.

As for the MacBook Pro, it is powered by both an Nvidia 9400M GPU and a 9600M GT GPU, while its Intel Core 2 Duo processors max out at 2.8GH, thus rendering the device the fastest portable computer of Apple’s updated line.

Less than one inch thick and weighing 5.5 pounds, the laptop has a 15.4-inch LED screen and features a high-resolution display, an ExpressCard slot, Firewire 800 for high-speed data transfer and a battery meter on the side.

All of the portable computers have a multitouch glass trackpad, which offers users a larger by 40 percent tracking area.
