Starting at the top, the MacBook Pro offers a new design, with an all-glass screen with black lipstick - similar to the current iMac. It also features a button-less glass trackpad, which is 39% larger than the previous one. The entire trackpad is in fact the button. The new MacBook Pro offers two GPUs (Nvidia GeForce 9400M and 9600M with 512MB of GDDR3 RAM) which you can run in Hybrid SLI mode. The displays are LED backlit, and the entire machine is constructed using a new manufacturing process that involves cutting the casing out of a solid block of aluminium, offering better rigidity. The USD 1999 model comes with a 2.4Ghz Intel Core 2 Duo (3MB L2), 2GB of DDR3 memory, SuperDrive, and a 250GB hard drive. There's also a USD 2499 model, which offers 4GB of RAM, and a 2.53Ghz processor. SSDs are an option. They're all 15.4" - the 17" model is also being updated, but doesn't receive the new design. On a final note, there is no option for non-glossy screens.
The ordinary MacBook receives many of the same features, including the new case design, the fancy manufacturing process, and the new Nvidia 9400M GPU (no second GPU, of course, that's a pro feature). There's a USD 999 model, which comes with the old Intel X3100 graphics chip and a 2.1Ghz processor, a USD 1299 model with the new Nvidia chip and a 2.0Ghz processor, and a top-of-the-line USD 1599 model with a 2.4Ghz processor, Nvidia chip, and a backlit keyboard. Unfortunately, the Macbook loses the Firewire port, leaving a lot of video and audio users disgruntled online.
The MacBook Air also received a minor update - it got the Nvidia chip, but throttled, a 120GB hard drive, while a more expensive model got a larger SSD (128GB) and a faster processor. All the new laptops sport the fancy new (Mini) Display Port connector.
Speaking of displays, Apple also introduced a new Cinema Display. It's 24", USD 899, and also sports the black lipstick and all-glass design. It has built-in iSight, it's LED backlit, 1920x1200 resolution, built-in speakers, and a built-in MAgSafe adapter to power your MacBook.
