The iBook G3/900 (Early 2003) was similar to the Late 2002 models before them and mostly consisted of increased RAM, processor improvements, and larger hard drives. The case of the Early 2003 models was the identical shape as the Late 2002 models. However, the Late 2002 models had a translucent white case while the Early 2003 case was opaque white.
The iBook G3/900 (Early 2003) featured a 900 MHz PowerPC 750fx (G3) processor, 128 MB of RAM, a 40.0 GB Ultra ATA hard drive, a tray-loading 8X/24X/10X/24X DVD-ROM/CD-RW Combo drive, and an optional AirPort (802.11b) wireless card. The display was a 12.1-inch TFT XGA active matrix display at 1024×768.
The design of these white iBook laptops greatly increased the mobility of the iBook line, compared to the much bulkier “clamshell” design of the original iBook laptops.
