HP has long had a love/hate affair with Linux. On the one hand, HP has long supported Linux on servers. For example, they're the one major server company that supports Debian. On the other hand, it took HP forever to finally start shipping pre-installed desktop Linux. Recently, for business users anyway, HP has been making it a lot easier to get Linux on their desktops and servers.

On the server side, for example, HP and Canonical, the company that stands behind Ubuntu, just announced that the newest version of Ubuntu, Ubuntu 9.04 has been certified the new HP ProLiant G6 servers.
