Do I need a laptop? No. So why am I consumed with techno-lust for the Apple iBook? The fastest iBook ever. Turbocharged with a blazingly fast 600MHz PowerPC G3 processor, 256K on-chip cache running at full processor speed, and a 100MHz system bus, the new iBook packs a tremendous wallop. And it comes with the ATI RAGE Mobility 128 graphics accelerator with 8MB of SDRAM and AGP 2X support for gorgeous 3D graphics.
