Soon, a new version of openSUSE will be released. It will bring many nice improvements, but for my part, the most important one is KDE 4.6. I think that I might have used this line before, but it's really what I do feel about KDE. "KDE 4 is finally ready for mainstream usage". KDE 4 in it's early releases was horrible to say the least.
KDE 4.6 is so much easier to use, and the overall experience just feels awesome, it doesn't get in my way while working with something, it just works and enables me to work in a more efficient way.
