Haiku

Haiku is not a Linux distribution, nor does it use the Linux kernel. Haiku is the spiritual successor to BeOS and it is derived from the NewOS kernel, which was authored by Travis Geiselbrecht (geist), who was formerly employed by Be Inc. — the developers of BeOS.

Linux-based distributions stack up software – the Linux kernel, the X Window System, and various DEs with disparate toolkits such as GTK+ and Qt – that do not necessarily share the same guidelines and/or goals. This lack of consistency and overall vision manifests itself in increased complexity, insufficient integration, and inefficient solutions, making the use of your computer more complicated than it should actually be.

Instead, Haiku has a single focus on personal computing and is driven by a unified vision for the whole OS. That, we believe, enables Haiku to provide a leaner, cleaner and more efficient system capable of providing a better user experience that is simple and uniform throughout.
