The third generation of PowerBook G3 (Lombard) was introduced in May 1999. It was much slimmer and lighter than its predecessor and was the first New World ROM PowerBook. It had longer battery life, and as with the Wallstreet II the user could double the duration to 10 hours by substituting a second battery for the optical drive in the expansion bay. The keyboard was also improved and now featured translucent bronze-tinted plastics, which is the origin of the "bronze keyboard" nickname. It was also the first Apple laptop with a backlit Apple logo on the rear of the display.
