New kid in town - Pinguy OS

Wanna try out Pinguy OS at the earliest
Check out: http://pinguy-os.sourceforge.net/

From the web-site:

Pinguy OS is an optimise build of Ubuntu 10.04 LTS Minimal CD with added repositories, tweaks and enhancements that can run as a Live DVD or be installed. It has all the added packages needed for video, music and web content e.g. flash and java, plus a few fixes as well. Like fixing the wireless problems, gwibber’s Facebook problem and flash videos in full-screen.

Everything is set-up for samba, all you need to do is right click a folder you want to share and add a password in samba using system-config-samba.
It also has a UPnP/DLNA server (pms-linux) so you can share your music, video’s etc. With a PS3, XBOX 360, Smart Phones or any other UPnP/DLNA media reader.
