It clocks in at #82 in the Top 100 of 2011 but remember, Linux Mint, Zorin, and probably other Linux distros are built upon the Ubuntu 11.04 codebase even though a newer version (Ubuntu 11.10) has been released which ruffled lots and lots of user feathers because of its Unity-only desktop.
This is a great accomplishment for Ubuntu 11.04, which is apparently the last one to include the beloved GNOME 2.3.2 Desktop. The alleged “new and improved” Ubuntu now looks like an iPad, which is exactly what’s driving Ubuntu users (like me) to Mint, Zorin and other Linux distros still embracing GNOME 2.x because it looks more like familiar old Windows than an iOS.
