Among all of the new hardware debuts Tuesday, Apple also quietly updated its wireless keyboard with a more energy-efficient model. The latest iteration of the Bluetooth
Apple Wireless Keyboard requires two AA batteries, down one from the previous model.
"And its intelligent power management system conserves battery life," Apple said. "So when you’re not using it, the keyboard automatically powers down. The instant you start typing, your keyboard turns on."
The new hardware requires a Bluetooth-enabled Mac computer, Mac OS X 10.5.8 or later with the Aluminum Keyboard Software Update 2.0, and an existing keyboard and mouse for initial setup. It comes with two AA batteries and costs $69.
The new keyboard was
first revealed in filings with the Federal Communications Commission earlier this month. It was approved at the same time as Apple's new
Magic Mouse.
