Ubuntu Software Center makes it easy

At some point I'm going to have to discuss the frustration with installing applications that are not found in the Ubuntu Software Center. However, at this time, it's good to know that there are plenty of options in each category a ton of applications to choose from in the Ubuntu Software Center (USC), and that using USC is easy.

You can browse by category if you don't know what specific application to look for. You can also search by a keyword and see a list of applications to choose from. 

You can install several alternatives and try them all. In the new v11, you can now try an app before you install it, which sounds pretty cool as well. Here in v10.10, however, that's not available. However, all applications are free, so if you install something and you don't like it, uninstall it with no worries (and no "registry" to declutter). 

Not everything is easy-peasy-lemon-squeezy in Ubuntu for the non-techies out there. When it comes to installing software, the Ubuntu Software Center is really helpful at making things easy.
