Why I Switched From Ubuntu To openSUSE
I have been using openSUSE for a few months now. I assume its been 3 months since I switched to openSUSE. I played with Gnome 3 Shell for a while and loved it. There is no doubt that openSUSE offers a great Gnome Shell experience. However, everything changed when I bought my second monitor and gave KDE a try.
Why I made the switch
While it is totally insignificant why I switched from my previous distribution to openSUSE, I would share the reason. I had been using Ubuntu since 2006 and when Ubuntu made a switch to Unity I found Global menus and extremely limited customization coming in my way. I was keeping a close eye on Unity development and when 11.10 was released it was clear that most of the customization that I wanted was not going to land in Ubuntu.
Using Unity became even more problematic when I bought my second monitor. I wanted to be able to use the second monitor more efficiently. Which was not possible with Unity.
