The Ubuntu community is built on the ideas: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. The Ubuntu distribution brings the spirit of Ubuntu to the software world.
Ubuntu operating system powers millions of desktop PCs, laptops and servers around the world. Ubuntu works with our existing PC files, printers, cameras, music players and smartphones - and it comes with thousands of free apps.

User Interface

The simplicity of Ubuntu's stylish, intuitive interface is very enjoying.Its have more than 20 desktop environments. Like: Unity, KDE, Gnome-shell, Enlightenment, Cinnamon, QTile etc.

Web Apps

If you use web applications like Facebook, Gmail or Flickr, you?re in for a treat. You can now pin them to the Launcher on the Ubuntu desktop and launch them with a single click. No more starting a browser, clicking on a bookmark and then logging in. Just go straight into the app, as if it was installed on your computer.

Online search

The Dash has always let you search your computer for your files, photos and videos. Now it does more than just search your computer - it can search your online accounts too. So, once you?ve saved the login details in the ?Online Accounts? function, you can expect to see your Flickr photos, Google Drive documents and more in your search results, alongside the files on your computer.

Dash previews

Ubuntu aims to take the effort out of everything. With Ubuntu 12.10, you can preview your search results in the Dash to see more options, without having to open more windows. Preview an album in the Ubuntu One Music Store and you?ll get the option to play tracks straight from the preview. And when you preview an app in the Ubuntu Software Centre, you can install it with just one more click.
