The idea of a notebook computer is that you can take it anywhere. So shouldn't it stand up to the occasional bump and jostle? The iBook is constructed from impact-resistant polycarbonate plastic and lightweight magnesium to provide durable computing power in a small, light package. It's configured with a 1GHz PowerPC G4 processor, a 512KB on-chip L2 cache, a 40GB Ultra ATA hard drive and 256MB SDRAM (expandable to 1280MB). In addition to the 133MHz bus speed, the iBook features a 24x16x24x8 (max. speeds) CD-RW/DVD-ROM combo drive, a FireWire port for digital video editing and high-speed peripherals and two USB ports for accessoires like Webcams and MP3 players. For your communications needs, both a 56K V.92 modem and 10/100Mbps Ethernet are built in. You can even go wireless with an optional AirPort Extreme card or Bluetooth module. The 14.1" TFT screen brings your games, applications and video to life with a 1024 x 768 maximum resolution supporting millions of colors.
