OpenElec

I' ve never come across this one before. So for me it's new. But this distro is actually specialized and I find highly interesting. And quite honestly, I probably wouldn't have bothered to post on this one. However, I'd like to give this distro the exception.

I neither use Apple TV nor Raspberry Pie. Nevertheless, I think this one is really cool if you like the Opensourced XBMC on your system and use it too. The other thing is that it's not Ubuntu based because quite honestly, the first thing that I thought of when I noticed this is that it would be Debian/Ubuntu based. However, it's not. It's quite independant. And in saying that, you won't find the usual office suites or tools pre-installed as is with many distros. This one is purely a default XMBC desktop. Really cool and very innovative I find. Good for these guys.

Check it out.

OpenELEC is a Linux-based embedded operating system built specifically to run XBMC, the open source entertainment media hub. The idea behind OpenELEC is to allow people to use their Home Theatre PC (HTPC) like any other device one might have attached to a TV, like a DVD player or Sky box. Instead of having to manage a full operating system, configure it and install the packages required to turn it into a hybrid media center, OpenELEC is designed to be simple to install, manage and use, making it more like running a set-top box than a full-blown computer.
