Ubuntu, no longer partaking in the suckfest. We have a long, enthusiastic review of Ubuntu 13.10 Saucy Salamander 64-bit edition, tested on a laptop with Nvidia graphics card in a dual-boot configuration, covering live session, look & feel, Wireless, Bluetooth, Samba sharing, Dash improvements and new options, partitioning, Ubuntu One login during installation, applications, multimedia playback - Flash and MP3, Nvidia driver setup, resource usage, performance, stability, printing, tiny niggles, and more. Enjoy.
