One of many good things in Ubuntu is there are a lot of free and open source which can be installed easily from repository. The official Ubuntu repository contains applications which predefined release schedule, so there might be some delay publishing an application update from its author to Ubuntu users. GetDeb and PlayDeb repository is an unofficial project which aims to provide the latest version of free open source software for Ubuntu. New software will be available as soon as released by the author. The main difference between GetDeb and PlayDeb is GetDeb offers the common software for Ubuntu while PlayDeb focused on publishing game for Ubuntu with easy install.
