Never intimidated by its larger siblings, the 13" MacBook Pro is the closest many users will get to the fabled 12" G4 Powerbook. Today's update gives it more to brag about, like extended battery life and improved performance.
This machine comes with either a 2.4GHz or 2.66GHz Intel Core 2 Duo processor. As with the other models, the 13" starts off with 4GB of RAM (upgradable to 8GB). The factory hard drive in this machine is smaller than in its siblings at either 250GB (2.4GHz) or 320GB (2.66GHz). Both are serial ATA drives at 5400 rpm (there's no 7200 rpm option for the 13" model) with the following upgrade path:
500GB Serial ATA Drive
128GB solid-state drive
256GB solid-state drive
512GB solid-state drive
Both feature a NVIDIA GeForce 320M for graphics and Apple's bold claim of up to 10 hours of battery life. They're using a technology called adaptive charging with these machines. Basically, a chip monitors the state of each battery cell and shares that information with the computer, which adjusts the current flowing into the batteries to suit its condition and requirements. Neat.
The 13" MacBook pro is available now and (as of this writing) ships within 1-3 business days. You can pick one up for US$1,199 (2.4GHz) or $1,499 (2.66GHz).
