Canonical has released Ubuntu 13.04, also known as “Raring Ringtail,” on the desktop. However, the release failed to thrill many reviewers, whose complaints included the point that Canonical had left out several features, including privacy protection and the Windows-based Ubuntu Installer. “In the reviews that I looked at, the main complaints were that Canonical had essentially dumbed down Ubuntu and made it more difficult to customize and personalize,” commented Charles King, principal at Pund-IT.
