MacBook Pro line of notebooks was updated today with the latest Intel Core 2 Duo processors and the memory was expanded up to 4GB.

Another improvement is that the new MacBook Pro is available in 15-inch models with a new mercury-free, power-efficient LED-backlit display and a 17-inch model with an optional high-resolution display.

“With Intel Core 2 Duo performance, more memory and state-of-the-art graphics, this MacBook Pro is a portable powerhouse for creative and professional users,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing.

“Apple’s notebooks have always led the industry in innovation with features like built-in 802.11 and the MagSafe Power Adapter, and now the industry’s first 15-inch LED-backlit display is another step toward completely eliminating mercury from our displays.”, he added.

The MacBook Pro is available with either 2.2 GHz or 2.4 GHz processors, and comes with a built-in iSight webcam. 

MacBookPro includes also Bluetooth, two FireWire ports, a DVI output, ExpressCard expansion slot, and a backlit keyboard.  The notebook is delivered with iLife pre-installed, which includes iPhoto, iMovie, and iTunes.

The 2.2 GHz model is selling for around $2000.  The 2.4 GHz unit comes with a 15-inch monitor for a list price of around $2500, or a 17-inch display for around $2700.
