RaspberryPiBoardDistributions

=Development environments=

Instead of just using compiler + editor, you can use complete image create "development tool chains" which integrate compiler, build system, packaging tools etc. in one tool chain.

Ubuntu
Ubuntu is currently listed as the default distribution on the Raspberry Pi website, but they have now stated they will not be supporting the ARMv6 architecture, so Ubuntu is likely to be dropped.

Eben says (regarding default distribution): "Either Ubuntu or Fedora; the main point in Fedora’s favour is their ongoing support for ARMv6 architectures."

Meego & XBMC
The MeeGo project provides a Linux-based, open source software platform for the next generation of computing devices. The MeeGo software platform is designed to give developers the broadest range of device segments to target for their applications, including netbooks, handheld computing and communications devices, in-vehicle infotainment devices, smart TVs, tablets and more – all using a uniform set of APIs based on Qt. XBMC is an award-winning free and open source (GPL) software media player and entertainment hub for digital media. Meego TV 1.2 uses XBMC as a reference GUI (that is, a starting point for creating a custom GUI).

RISC OS
RISC OS is a fast and lightweight computer operating system designed in Cambridge, England by Acorn. First released in 1987, its origins can be traced back to the original team that developed the ARM microprocessor. RISC OS includes BBC BASIC which was primarily conceived to teach programming skills as part of the BBC computer literacy project.
