Canonical have release version 11.10 of their desktop Linux distribution. I have been using Ubuntu for quite a while now but was not a fan of the unity desktop released in 11.04 and had switched to the standard Gnome desktop. I am glad to say that with the latest release Canonical are back on track and a lot of the issues have been resolved. The first thing that strikes you is how well it looks. It is very polished and professionally finished. The unity desktop now works as it should and is seamless you will be comfortable using it within minutes. This version comes with Libre Office 3 and Firefox which for most people is all they need. Performance is also good and desktop animations are very smooth.
If you are a Ubuntu user it is definitely worth upgrading. For me I am now only using Windows for .Net development. Everything else is available on Linux.
