From Engadget:

Today Intel announced details of their new all-in-one wireless

chip — integrating 802.11a/b/g and ready-for the yet to be ratified +100Mbps

802.11n — something that currently requires

several chips. They even figured out a way to integrate formerly extraneous bits like power amplifiers.

An iBook running an Intel chip, with EFI instead of BIOS, and with this wireless chip that'd presumably have open-sourced Linux drivers would be a mean, lean Linux machine. Dual-booting Linux and OS X, with Windows apps running speedily under VMware or Virtual PC, yum.
