KDE Developer Frank Karlitschek has an ambitious plan of providing a computer system dedicated entirely to Linux, for consumers. Announced at Gran Canaria Developer Summit, Frank's slides and presentation talk about the dire need for GNU/Linux systems to have a fully open-specification machine.
The project seems to be still in its infancy, and the projected date for shipping seems oddly optimistic. (By Fall?! Really?!). Still, Frank seems to be working hard at collecting user opinions and is open for ideas, so check out the project's website. More on this as it develops.
