Today, Apple announced a minor enhancement to the PowerBook line, a major addition to the Power Mac line, and the November release of Aperture.

The 15″ and 17″ models of the PowerBook line have received higher screen resolutions and an extra hour of battery life. Though the media is highlighting the enhanced resolution and battery life of the PowerBook line, the best enhancements to the PowerBook line are its newly lowered prices.

A “Quad” 2.5GHz model, with two dual-core G5 processors, was added to the Power Mac line. It’s 10GHz of computing power at a some-what affordable price, for those of you with an extra $3,299.

Apple claims that Aperture is “the first all-in-one post-production tool for photographers.” Contrary to popular belief, Aperture is much more than “iPhoto on steroids”. If you don’t believe me, I highly recommend that you watch the video tours of Aperture’s key features.
