Dell has expanded their Linux desktop offerings today, announcing that they have made "select" systems available with Ubuntu Linux 8.04. The Hardy Heron distro is an upgrade from the existing Dell Linux Desktops which came with 7.04/7.10. Dell is making the XPS M1330N, Inspiron 530N and the Inspiron 1525N machines all available with Linux pre-loaded via their website.
Though the overall hardware profile that Dell offers with desktop Linux is small, it's still a change from years prior, when it was absolutely nothing. The change of heart came last year after Dell noticed increasing demand for an alternative to Windows.
