Ubuntu 9.04 Desktop Edition delivers a range of feature enhancements to improve the user experience. Shorter boot speeds, some as short as 25 seconds, ensure faster access to a full computing environment on most desktop, laptop and netbook models. Enhanced suspend-and-resume features also give users more time between charges along with immediate access after hibernation. Intelligent switching between Wi-Fi and 3G environments has been broadened to support more wireless devices and 3G cards, resulting in a smoother experience for most users.
A new integrated notification system appears in Ubuntu 9.04 for the first time. This system combines the notification methods of various applications and presents that information in a simple, unobtrusive manner. New icons and artwork also appear in this release, part of the continual improvement of the Ubuntu user experience.
