This is my main system, a Elite A531 laptop, with a Crusoe processor. It is running Gentoo, with linux kernel 2.6.7. It has, amongst other things, an embedded USB WLAN controller.
This is a self-assembled system.
This is a very nice router from Linksys. It runs Linux 2.4, has a DHCP server, performs NAT and other interesting stuff. It was a very good deal for less than 80 EUR.
