Apple announced its upgrades for both MacBook and MacBook Pro portables, adding Intel 45-nanometer Penryn architecture for its Core 2 Duo processors. All systems now include the larger Level 2 cache, SSE4 media instructions, and reduced power consumption of the new chips.

The MacBook Pro now receives the multi-touch trackpad from the MacBook Air and also adds the first LED backlighting option for the 17-inch display; choosing the high-resolution, 1920×1200 screen also adds the more color-accurate backlight and potentially extends battery life. Video memory has also been doubled across the line.

MacBook Pro prices start at $1,999 for a 2.4GHz 15-inch system with 2GB of memory, a 200GB hard drive, a dual-layer Superdrive, and a GeForce 8600M GT with 256MB of video memory; the $2,499 mid-range model boosts speeds to 2.5GHz, expands storage to 250GB, and introduces a 512MB GeForce 8600M GT chipset. The 17-inch model sells for $2,799.

The standard 13.3-inch MacBook goes without the advanced trackpad but receives a major upgrade to both its performance and storage. The standard 2.1GHz model adds both the Intel Penryn and boosts storage to 120GB. Moving to the mid-tier, $1,299 model increases speed to 2.4GHz, doubles the amount of RAM to 2GB, and jumps to a 160GB hard drive as well as a dual-layer Superdrive. A black 2.4GHz model at $1,499 adds a 250GB hard drive.

All five systems are available to order immediately from the online Apple store .
