During this year’s WWDC Apple announced a significant breath of life to their MacBook laptop series. The changes bring a completely revamped 15” MacBook Pro, and upgrades to the 13” and 17” models. Also, undergoing a name-change, the 13” MacBook is now officially a member of the MacBook Pro family.

All of the models now include a built-in battery, which provides up to 7 hours of battery life – a dramatic 40% increase. Other mutual features include an LED-backlit display with improved color intensity, an illuminated keyboard, an SD card or ExpressCard slot, a FireWire 800 port and Nvidia graphics.

The 13” model kicks things off with base components including a 2.26GHz Core 2 Duo, 2GB DDR3 RAM, an Nvidia GeForce 9400M and a 160GB HDD. Pressing forward, the stock 15” MacBook packs a 2.53GHz Core 2 Duo, 4GB DDR3 RAM, a GeForce 9400M/9600M and a 250GB HDD. At the head of the pack, the 17” features a 2.8GHz Core 2 Duo, 4GB DDR3 RAM, a 9400M and 9600M with 512MB VRAM, and a 500GB HDD.

Prices have come down across the board. The 13” starts at $1,200, the 15” at $1,700, the 17” at $2,500 and the MacBook Air at $1,500 – all of which are available now.
