Computer manufacturer ASUS has published the Linux source code for its Seashell line of netbooks. Previous to the companies Seashell line up, ASUS netbooks were often available with Linux as an option for the pre-installed operating system (OS), usually at a lower price. With the release of its current Seashell models, the 1008HA and the 1005HA, however, Windows XP has been and still is the only pre-installed OS option available.
