Channel Register posted a review on Ubuntu 9.04, which will be released later today
Jaunty Jackalope brings quite a few changes for Ubuntu users, including Canonical's controversial decision to include a new notification system and message-indicator applet. The Canonical-developed notifications system is designed to offer updates in an unobtrusive way - a small window pops up and informs you of events such as new e-mails and instant messages as well as system events such as changing the volume or when a CD finishes burning.Ubuntu 9.04 Review
The messages themselves look a bit like the Growl notification system in Mac OS X, and we found them to be a pleasant and informative system. But of course, the messages represent a major departure for Ubuntu, and those of you who dislike it when Linux distributions include experimental features - rather than sticking with the stock GNOME components - may not be thrilled.
