Besides Ubuntu as an OS on my machine, I’m also using Debian GNU/Linux 7 Wheezy for months now. I’m enjoying using this latest stable version of Debian because it really is a stable version. I never encounter a single error while using it. That’s the main reason why I choose to use it for some stuff I’m doing. If you are looking for a stable OS and have never use Debian before, I highly recommend to install and use it.
